It was the most successful political marriage of the century, right up until the moment it wasn't. For years, the deal was simple: Donald Trump provided the signatures, and the Federalist Society provided the judges. It was a conveyor belt of Ivy League-educated, originalist-minded legal talent that reshaped the Supreme Court and the lower benches for a generation.
But by early 2026, the vibe shifted. Hard.
If you’ve been watching the headlines lately, you’ve probably seen the cracks. We’re no longer in the era of "Leonard Leo’s wishlist." Instead, we’re in an era where Trump openly calls Leo—the architect of his first-term judicial legacy—a "sleazebag." It’s a wild turnaround. How do you go from appointing three Supreme Court justices in four years to calling the guy who helped you do it an "America-hater"?
The answer lies in a deep-seated Federalist Society Trump ambivalence that has finally boiled over. It's not just a personality clash; it’s a fundamental disagreement about what "conservative law" even means.
The Loyalty Test vs. The Constitution
The friction really started to spark when judges appointed by Trump—the very people recommended by the Federalist Society—started ruling against him.
To Trump, a judge is basically an employee. He expects results. When a panel of conservative judges blocked his 2025 tariffs or ruled against his move to seize control of independent agencies like the FTC, he didn't see "principled originalism." He saw betrayal.
The Federalist Society has always been a "big tent" for people who believe in a limited federal government and a strict reading of the Constitution. But many of those members are libertarians or free-marketeers. They don't necessarily like Trump’s "America First" economic nationalism or his theories of the Unitary Executive.

Honesty, the tension is baked into the DNA of the movement. You've got:
- The Originalists: These folks care about the text of 1787. If the law says the President can't do $X$, they'll rule against him, even if he appointed them.
- The Populists: This newer wing, often called "Common Good Constitutionalists," thinks the law should be used to achieve specific conservative social or nationalistic ends.
- The MAGA Loyalists: They want "fighters." They think the Federalist Society is too "establishment" or too concerned with what the New York Times thinks of them.
Why Trump Turned on Leonard Leo
Leonard Leo was the kingmaker. For decades, he was the guy you had to see if you wanted a seat on the federal bench. But Trump’s recent social media broadsides against Leo reveal a massive rift.
Trump recently lamented that he took "bad advice" during his first term. He’s essentially saying he wants judges who are loyal to him personally, not to a specific legal philosophy. He’s tired of the "Ivory Tower" intellectuals. This is why we’re seeing him bypass the traditional Federalist Society pipeline in favor of his own defense lawyers—people like Emil Bove—for judicial nominations.
It’s a strategic pivot. By ditching the Society's vetting process, Trump is trying to build a judiciary that won't "abandon" him when his executive orders get challenged in court.
The Unitary Executive Theory Blowup
One of the biggest flashpoints in 2025 and 2026 has been the Unitary Executive Theory. This is the idea that the President has absolute control over everything in the executive branch.
Trump’s team loves this. They’ve used it to try and fire independent agency heads and bypass Congress on spending. But here's the kicker: many Federalist Society scholars actually hate this. They think it smells too much like a monarchy. When conservative judges started using "originalism" to reject this theory, Trump realized the monster he helped create—the conservative judiciary—wasn't going to be a rubber stamp.

Is the Federalist Society Losing Its Grip?
Kinda. But also, no.
While Trump might be moving on to "thugs and hacks" (as some critics put it), the Federalist Society still controls the intellectual infrastructure of the right. They have the students. They have the clerkships. They have the donors.
The Society has always officially taken "no position" on policy. This gives them a sort of "plausible deniability" when their members disagree. But internally, the debate is fierce. Can you be a "good" conservative and still rule against a Republican president? Most FedSoc members would say "yes, obviously." Trump would say "absolutely not."
That’s the core of the Federalist Society Trump ambivalence. It’s the difference between a movement based on ideas and a movement based on a leader.
What This Means for Future Judges
If you're following judicial nominations right now, the landscape looks totally different than it did in 2017.
- Vetting is moving in-house: The White House Counsel’s office and personal loyalists are doing the screening now, not Leonard Leo’s network.
- Loyalty over Credentials: We're seeing fewer "Gold Medal" resumes from top-tier law schools and more people who have proven their "fight" in the political trenches.
- The "Blue Slip" is Dying: There's immense pressure to ignore traditional Senate norms to get these loyalists confirmed quickly.
What Most People Get Wrong
People often think the Federalist Society is a monolith. It’s not.

It’s a debating society that became a power broker. There are plenty of people in the group who find Trump’s rhetoric exhausting and his legal theories dangerous. Conversely, there are younger members who think the old guard is too soft and "too obsessed with procedure" while the country "burns."
This split is the most important thing happening in the legal world right now. It determines whether the "rule of law" remains an objective standard or becomes just another tool for whoever holds the White House.
Real-World Impact: Trump v. Barbara
Look at the 2026 case Trump v. Barbara. This is the big birthright citizenship challenge. The Federalist Society is all over this—but on both sides. You’ve got professors like Randy Barnett and Michael Ramsey debating the 14th Amendment’s "subject to the jurisdiction" clause.
In the past, the Federalist Society would have been the united front providing the legal muscle for the administration. Now? They’re the ones providing the most sophisticated arguments against the President's executive overreach.
Actionable Insights for the Legal Observer
If you’re trying to navigate this new era of conservative law, keep these things in mind:
- Watch the Nominations: Don’t just look at where a judge went to school. Look at their history of personal loyalty to the Trump administration. If they didn't come through the Leonard Leo pipeline, expect a different kind of jurisprudence.
- Follow the Blogs: Sites like the FedSoc Blog are where the real war is happening. Look for posts that use "originalism" to critique "executive power." That’s where the resistance is hiding in plain sight.
- Understand the "Common Good" Pivot: The "Common Good" legal movement is the MAGA alternative to traditional Federalist Society originalism. If you see a nominee talking about "natural law" or "national interest" over "textualism," they are likely part of the post-FedSoc wave.
- Check the Amicus Briefs: In big Supreme Court cases, look at which conservative groups are filing briefs against the administration. If it’s a group with deep FedSoc ties, you’re seeing the ambivalence in action.
The divorce isn't final yet. Trump still needs conservative votes in the Senate, and those Senators still love the Federalist Society. But the honeymoon? That's been over for a long time. The "sleazebag" comments were just the public filing of the papers.
To stay ahead of how this affects the courts, you should track the specific law firms and groups (like the NCLA or Boyden Gray) that are increasingly finding themselves at odds with the administration’s more radical executive theories. That is where the next decade of American law will be decided.
