COLUMN: Trump Against His Own Senate — The Republican Civil War Paralyzing Washington

Introduction: The Legislature Held Hostage by Its Own Executive

When the Ally Becomes the Obstacle

There is a truth that political science textbooks have repeated for decades: governing with a parliamentary majority is harder than governing against the opposition. You can fight the opposition. Your own allies must be managed — and Donald Trump, in his second term, seems incapable of telling the difference between the two. In June 2026, Washington is the stage for an unprecedented confrontation: the President of the United States is actively sabotaging the legislative victories of his own Republican Senate allies, creating an institutional paralysis whose consequences could be felt well beyond the current session.

This is not an ideological war. The Republican senators opposing Trump are not challenging his broad direction — immigration hardline, tax cuts, American rearmament. What is breaking them is the methods: the unpredictable reversals, the surprise nominations that torpedo patiently constructed compromises, the impossible demands formulated at the last moment when votes are already scheduled. Trump is not fighting over ideas against his Senate. He is fighting for absolute control — and the Senate, in its moments of resistance, reminds him that the Constitution does not grant it.

The Clayton and FISA Affair: A Textbook Case in Disorganization

The Jay Clayton and FISA dossier — the Foreign Intelligence Surveillance Act — perfectly illustrates this destructive mechanism. For weeks, Republican senators had patiently negotiated a three-part agreement: confirm Clayton as Director of National Intelligence, renew FISA for three years, and satisfy certain guarantees sought by members most concerned with civil liberties. The agreement held. Clayton's confirmation was, according to several senators, on track for a vote by Thursday.

Trump then announced without warning the designation of Bill Pulte — a political ally who ran a housing agency — as acting Director of National Intelligence. This unilateral decision immediately torpedoed the agreement under construction. The senators who had worked on the compromise were blindsided. The FISA deal collapsed. Clayton fell back into uncertainty. And according to Politico, the administration had itself previously argued that FISA renewal was crucial to protect Americans during the World Cup and America 250 celebrations. Trump had just killed his own security priority.

Article II and Its Limits: What the Constitution Imposes on Trump

The Separation of Powers Is Not Optional

At the heart of the tension between Trump and his Senate lies a fundamental constitutional question. Article II of the U.S. Constitution defines presidential powers. These powers are considerable: commander in chief of the armed forces, treaty negotiator, guardian of law enforcement. But they are expressly tempered by Article I, which grants Congress distinct and sovereign competencies: raising taxes, declaring war, approving treaties, confirming nominations. These two articles coexist in a constitutional tension deliberately designed to prevent the concentration of power.

Trump systematically treats this tension as an obstacle to overcome rather than a principle to respect. His repeated attacks on the filibuster rule — which requires 60 votes to close a Senate debate, forcing bipartisan consensus — are the most glaring example. He presses his senators to abolish this rule to pass his bills by simple majority. The vast majority of the Republican Senate refuses: they know that a filibuster abolished today for Trump's benefit will be abolished tomorrow for a Democratic president's benefit. Thom Tillis put it with precision: "We are not the Article II manufacturing department — we are its board of directors."

Blocked Nominations as an Institutional Barometer

Presidential nominations have become the main battlefield between Trump and his Senate. The Constitution requires the Senate to confirm nominations to the most important executive positions — cabinet members, ambassadors, federal judges, agency directors. This confirmation right is not a procedural detail: it is a central mechanism for checking executive power. When Trump bypasses this mechanism via acting nominations, he strips the Senate of its constitutional role and creates executive officials who are directly accountable to him without passing through the Senate filter.

The nomination of Pulte as acting Director of National Intelligence is precisely of this order: by not submitting a regular nomination for confirmation, Trump installs a loyalist in a sensitive position without subjecting him to Senate questioning. This practice of acting nominations, used selectively in previous administrations, has become systematic under Trump — and it generates growing frustration among Republicans who see their constitutional role progressively hollowed out.

The January 6 Fund: The Final Affront

One Billion Eight Hundred Million for the Capitol Rioters

If a single episode illustrates Trump's capacity to dynamite his own legislative victories, it is the surprise announcement of the $1.8 billion compensation fund for those he considers victims of political persecution — notably participants in the assault on the Capitol on January 6, 2021. This announcement, made without prior coordination with Republican Senate leaders, came in the middle of negotiations on a crucial immigration agency funding bill. It nearly killed a vote the administration itself had demanded.

The reaction of Republican senators was remarkably candid. Thom Tillis called the fund "payment for punks" and "stupid squared."Bill Cassidy joined an amicus brief filed in court to challenge the fund. Several senators simply left Washington and refused to sit — a rare act of collective legislative resistance under Trump. The administration ultimately backed down, indicating the fund was "not moving forward." But Tillis and others demand a formal legal guarantee, not merely a verbal promise.

The Immigration Funding Bill: Saved by a Razor's Edge

The immigration agency funding bill — a Republican Party and Trump administration priority — ultimately passed, but in an internal crisis context that exposed the fragility of the majority. Eight Republican senators voted for at least one Democratic amendment during the process — a remarkable deviation in a normally disciplined party. Among them: Cassidy, Collins, Murkowski, and senators facing difficult elections in November. The bill passed, but the scar remains: the Republican caucus is not monolithic and Trump knows it.

The SAVE America Act: A Battle Lost Before It Begins

The Electoral Obsession That Divides Republicans

One of the deepest sources of tension between Trump and his Senate is the SAVE America Act — an election law that would require proof of citizenship to register to vote and a photo ID to cast a ballot. Trump has made it an absolute priority for years, presenting it as a defense against electoral fraud — fraud for which, according to the researchers and judges who have examined his allegations, no systemic evidence exists.

To pass this bill, Trump demands the Senate abolish the filibuster. Republican senators refuse. The Senate is in a deadlock that Trump describes on Truth Social as betrayal: "Look what's happening in California; the Dumocrats are stealing the vote right before our eyes." The White House suggests that Senate inaction is incomprehensible: "It shouldn't be a surprise. They've been hearing about this for three years." But Republican senators, knowing the bill cannot pass with 60 votes and unwilling to abolish the filibuster, remain at an impasse.

The Art of the Impossible: When Trump Demands the Undeliverable

The SAVE America Act illustrates a recurring problem in the Trump-Senate relationship: the president formulates demands he knows are impossible to fulfill under current rules, then blames Congress for not fulfilling them. This rhetoric has a useful political effect — it allows him to mobilize the MAGA electoral base against Republican "traitors" — but a devastating institutional effect: it poisons relations with legislative allies who need collaboration to advance on shared priorities.

According to Politico, the mood behind closed doors in the Republican Senate is increasingly tense. Senators who have spent years publicly supporting Trump privately express rising frustration. They have their own priorities, their own states, their own electoral calculations for November 2026. And the image of a president who shoots them in the back — announcing measures that sabotage their negotiations at the last moment — is beginning to seriously erode several senators' loyalty.

Pulte and National Intelligence: A Nomination That Sows Chaos

From Housing to Intelligence: The Logic of Loyalty

The nomination of Bill Pulte as acting Director of National Intelligence perfectly embodies Trump's governing philosophy: place loyalists in key positions regardless of their experience in the relevant field. Pulte is a Trump ally who ran the Federal Housing Finance Agency — the mortgage market regulator. Nothing in that background predisposes him to oversee the American intelligence community, which includes the CIA, NSA, FBI, and a dozen other agencies.

His designation as acting director — rather than a formal Senate-confirmed nomination — is precisely designed to bypass the process that would have allowed senators to question his qualifications. This is the acting nomination game: place someone quickly, without a filter, with the authority of a confirmed director but without the legitimacy of a Senate vote. And in this specific case, the maneuver not only circumvented the Senate but also torpedoed three years of work on FISA renewal — a law the administration itself considered urgent.

FISA: The Surveillance Tool Trump Accidentally Killed

The Foreign Intelligence Surveillance Act — FISA — is one of the most powerful tools of the American intelligence community for monitoring the communications of foreign adversaries operating on U.S. territory. Its renewal every few years is an obligatory passage that generates bipartisan tensions over the balance between national security and civil liberties. In 2026, a three-party agreement had been under construction for months, with a majority of Republican and Democratic senators ready to vote for renewal.

The Pulte nomination blew everything up. The senators working on the agreement refused to validate a situation in which the person charged with overseeing FISA-covered operations was an unconfirmed acting official, placed there by an impromptu presidential decision. The vote was postponed. FISA, whose validity is time-limited, remains without renewal. And the Trump administration finds itself in the paradoxical position of having itself blocked an intelligence tool it had presented as vital.

The Senate Nomination Rule: Another Battlefield

The "Home-State Deference" Trump Wants to Abolish

Beyond the filibuster, Trump has also attacked the informal rule of "home-state deference" — the Senate tradition by which senators from a nominee's home state have a particular say in that nomination. This unwritten rule is a brake on nominations Trump would like to push through quickly: it allows a single state senator to indefinitely block or slow a confirmation by refusing to return the consent form.

Tillis has made strategic use of it — notably to block Kevin Warsh's nomination to chair the Federal Reserve until obtaining guarantees on Fed independence. This use of internal Senate rules as a negotiating tool is precisely what Trump denounces as obstruction. But these rules exist for a reason: they are the levers of a Senate that refuses to be transformed into a rubber stamp for the executive. Tillis repeats this with disarming clarity: the Constitution requires it.

Institutional Acceleration as a Systemic Danger

What Trump asks of his Senate — abolish the filibuster, eliminate home-state deference, accelerate confirmations, pass laws by simple majority — constitutes, taken together, a program for dismantling the institutional checks on legislative power. Individually, each of these measures can be defended on pragmatic grounds. Collectively, they would transform the Senate into a chamber subordinate to the presidential executive — precisely what the American Constitution sought to prevent.

The Senate as an Institution: The Long History of Executive-Legislative Tensions

Wars That Shaped American Democracy

The tension between the Senate and the president is nothing new. American history is dotted with major confrontations between the two branches. Andrew Johnson nearly faced removal for violating the Tenure of Office Act. Franklin Roosevelt attempted to "pack" the Supreme Court to make it favorable to his New Deal — and was blocked by his own Congress. Richard Nixon was forced to hand over his phone recordings by a congressional vote. Barack Obama used executive orders to bypass a gridlocked Congress — which Republicans then denounced as an assault on separation of powers.

What distinguishes the current situation is the intensity of the intra-partisan confrontation. Historically, major executive-legislative tensions pit different parties against each other. Seeing a Republican president in open war with Republican senators — sabotaging their victories, attacking them personally, attempting to strip them of their constitutional prerogatives — is more unusual. It is the sign of a Republican Party in profound transformation, where personal loyalty to Trump has replaced, for the vast majority, loyalty to institutional norms.

What History Says About Presidents Who Ignored Their Own Congress

Presidents who systematically ignored or attacked their own legislative bloc have generally ended their terms badly or left their successors with weakened coalitions. Lyndon Johnson, whose grip on Congress was legendary, worked with his allies — sometimes brutally, but always with a logic of legislative results. Trump works more against his Senate than with it. The results show: the legislative calendar is chaotic, priorities accumulate without being addressed, and the approach of the 2026 midterms without a solid legislative record weakens Republican candidates seeking to justify their performance to voters.

The Impact on the Midterms: A Majority That Crumbles

The Republican Survival Strategy in Swing States

For Republican senators running for re-election in November 2026, the internal civil war is a major electoral headache. Supporting Trump 100 percent satisfies the MAGA base but alienates moderate and suburban voters who voted Republican in 2024. Criticizing Trump satisfies moderates but exposes them to a destructive primary campaign from a Trumpist challenger. Most choose a third path: careful silence, veiled criticism, voting with the majority on key bills while privately suggesting a certain distance.

This survival strategy is politically understandable but institutionally costly. It deprives the Senate of a coherent collective voice against an executive seeking to control it. And it guarantees that the Trump/Senate dynamic will continue to deteriorate: Trump will continue pushing his extreme demands, the Senate will continue to resist feebly, and the result will be an accumulation of unresolved dossiers and legislative deadlocks that Democrats will exploit in their campaigns.

At-Risk Seats and the Arithmetic of Possible Defeat

Senate arithmetic is merciless. Republicans are defending seats in states where Trump won narrowly or lost in 2024. Ohio, Alaska, Maine — states where the Republican candidate needs moderate votes that the MAGA brand alone cannot deliver. The internal civil war between Trump and his Senate hurts this coalition strategy: it reinforces the image of a divided and chaotic party, incapable of governing effectively even when it holds all majorities.

The Budget Dimension: "Reconciliation 3.0" and Its Uncertainties

A Third Round of Budget Reconciliation?

Beyond nomination and procedural confrontations, the Trump/Senate tension also has a concrete budgetary dimension. Discussions have begun on what some legislators describe as "Reconciliation 3.0" — a third round of budget legislation through reconciliation procedure, which allows fiscal and spending laws to pass by simple majority without filibuster risk. But prominent Republican senators express marked skepticism: is it really possible to finalize a third reconciliation bill before the November midterms, with so few legislative weeks available?

The potential priorities for this reconciliation — new tax cuts, border wall construction funding, cuts to certain social programs — are all politically sensitive for senators in swing states. And the experience of the first "One Big Beautiful Bill" showed that even with a formal majority, passing these texts generates considerable internal friction. Senators watching November 2026 polling numbers are not necessarily enthusiastic about another vote on Medicaid cuts or tax reductions primarily benefiting the wealthy.

The Deficit as a Reality Ignored in the Tax Debate

Another point of friction, less visible in the headlines, is the question of the federal deficit. Several moderate Republican senators — including Tillis before his departure — have expressed concerns about the impact of repeated tax cuts on the long-term deficit. Trump, who has always had a complex relationship with fiscal discipline, does not consider this question a priority. But in a context of high interest rates and federal debt refinancing at far less favorable terms than ten years ago, senators looking beyond their next electoral cycle see a structural problem that Trumpism does not address.

The Long-Term Institutional Dynamic

What This Civil War Does to Unwritten Norms

Unwritten norms — the institutional conventions that govern the behavior of political actors beyond what the law imposes — are perhaps the primary victim of the Republican civil war. The filibuster, home-state deference, collegial nomination confirmation, respect for agreements under construction: all these practices rest on a culture of minimal trust between institutional actors. That culture erodes when a president repeatedly attacks his own allies, cancels agreements at the last moment, and treats the Senate as an obstacle rather than a partner.

What is destroyed in this process is difficult to rebuild. Institutional norms take decades to form — they are born from repetitions, from precedents, from accumulated trust. They can be destroyed within a few years by actors who deliberately ignore them. And once destroyed, future occupants of power will inherit a harsher, more transactional institutional environment, more conducive to abuse of power of every political color.

The Lesson for Liberal Democracies

The West watches with concern the American institutional dysfunction. Not only because the United States is the natural leader of the democratic alliance against Chinese, Russian, and Iranian authoritarian threats — real threats that demand a united and functional America. But also because America is, for many younger democracies, a model and a reference. When this model shows its limits — when the Senate and the president from the same party wage war, when institutions erode under the pressure of personal loyalty — the message sent to fragile democracies worldwide is alarming.

The Senate's Constitutional Resistance Options

What the Senate Can Do Without Trump

Facing an executive that short-circuits its prerogatives, the Senate has several constitutional tools. Blocking nominations through internal rules — used by Tillis on Warsh — is one. Budget oversight — voting or refusing to vote appropriations requested by the executive — is another. War powers oversight resolutions — such as the one voted on Iran with Cassidy's support — constitute a third lever. And the power of congressional investigation — summoning witnesses, requesting documents, making public information the executive would prefer to keep confidential — is the fourth.

These tools exist. Their use depends on senators' willingness to activate them — and their political calculation of the electoral cost of open confrontation with Trump. For now, only a few members of the YOLO caucus use them systematically. But if the Republican civil war continues to intensify, if the November 2026 midterms vindicate the internal Cassandras, more senators may join the movement. Electoral defeat is often the best teacher of institutional courage.

The Historical Precedent of Majorities That Resist Their Own President

There are historical precedents of parliamentary majorities that have managed to resist their own chief executive. In France, cohabitation majorities have worked. In Britain, rebel caucuses have forced prime ministers to back down. In the United States, the Republican Senate of the late 1970s forced Gerald Ford to retreat on several fronts. These episodes show that institutions can resist — but they only resist if political actors choose to defend them, at the cost of considerable personal and political conflict.

The Frustration of Republican Congressional Staff

Behind the Scenes of Institutional Anger

Behind senators' measured public statements, Republican congressional staff and aides express far more direct frustration. According to multiple sources cited by Politico under cover of anonymity, the atmosphere in Republican Senate offices is marked by a growing sense of powerlessness. They work for weeks building fragile majorities on complex dossiers — FISA, confirmations, budget bills — only to be short-circuited in a few hours by a tweet or an impromptu presidential announcement. The president, in this view, is less a strategic ally than an uncontrollable variable.

This frustration among congressional staff has concrete consequences for legislative effectiveness. When aides no longer know whether agreements will hold until the vote, they stop investing the energy necessary to build them carefully. When senators cannot predict what the White House will say tomorrow about a dossier it supported yesterday, they hedge their positions, avoid necessary compromises, and the legislative calendar expands indefinitely. The result, visible for months in Washington, is a government that formally runs but does not produce the results its own members demand of it.

Republican Whips Facing the Impossible

Whips — those responsible for vote-counting within the Republican caucus — are in a particularly difficult situation. Their role is to count votes, identify potential dissenters, and negotiate the compromises that allow bills to pass. Under a normal administration, they work in close coordination with the White House to align signals sent to members. Under Trump, they must often manage last-minute presidential surprises that overturn their calculations and cost them votes they thought secured. The story of the January 6 participant compensation fund illustrates this perfectly: announced without warning, it immediately flipped several Republican votes the whips had counted as certain on the immigration vote.

This dysfunction in legislative coordination between executive and legislature has a direct cost on the government's capacity to act. And it feeds the sense, among several Republican senators, that Trump cares more about media dynamics and his base's response than about actual legislative results. This perception — founded or not — is itself a factor that further weakens Republican majority cohesion at crucial moments.

The View of European Allies on American Dysfunction

A Reliable or Unpredictable America: The Question Europe Must Ask

For America's European allies — who depend on American consistency in areas as critical as NATO defense, sanctions against Russia, China policy, and global financial architecture — the Republican civil war in Washington is a source of deep concern. Not only because it weakens American legislative capacity, but because it signals a governance instability that makes American commitments harder to credibilize. When Congress and the president are not speaking, when agreements form and dissolve within hours, the allies negotiating with Washington never know which promises to count on.

European leaders, who have learned to function with Trump's unpredictability since 2017, have developed adaptation strategies: strengthening European strategic autonomy, building bilateral agreements less dependent on Washington's consistency, diversifying security partnerships. These strategies are rational in the face of American instability. But they come at a cost: they erode transatlantic cohesion precisely at the moment when the Chinese and Russian threat demands a unified Western response. What Trump does to the Republican Senate, he does also, indirectly, to the Western alliance.

The Asian Perception: China and Japan Read the Signals

Asian actors are also reading with close attention the signals sent by American institutional dysfunction. Beijing sees in the Republican civil war confirmation of its thesis that liberal democracy is a system structurally incapable of making coherent and sustained long-term decisions. Every episode of American legislative gridlock, every confrontation between Trump and his Senate, every last-minute presidential reversal feeds the Chinese narrative about the superiority of the authoritarian governance model. This is an influence war as much as one of tanks and missiles — and on this terrain, Washington is currently shooting itself in the foot.

Conclusion: A Republican Civil War With Global Stakes

What Happens in Washington Goes Beyond Washington

The Republican civil war between Trump and his Senate is not merely an internal power struggle within an American political party. It is the sign of a deep tension between two visions of exercising power in a liberal democracy: one that respects constitutional checks as guarantees of collective freedom, and one that sees them as obstacles to an efficient strong executive. This tension runs through all Western democracies right now. What is happening in Washington offers its most spectacular and most consequential version.

Institutional Resilience: Neither Guaranteed Nor Assured

What the Trump/Senate confrontation teaches, ultimately, is that the resilience of democratic institutions is neither guaranteed nor assured. It depends, in every generation, on the willingness of individual political actors to defend norms that do not personally benefit them — or that only benefit them in the long run. The YOLO caucus, the Tillis and Cassidy of the passing moment, are an imperfect and belated illustration of this possible resilience. The West needs a strong America, institutionally sound, capable of fulfilling its role as leader of the democratic alliance. That America is built in the Senate as much as in the White House.
