Sen. Thom Tillis, the retiring North Carolina Republican, went on CNN Sunday and called for White House deputy chief of staff Stephen Miller to leave President Trump's inner circle.
Tillis told Jake Tapper on "State of the Union" that Miller has been "repeatedly responsible for embarrassments" and should be relieved of his duties.
When Tapper asked directly whether Miller should go, Tillis didn't hesitate: "Oh, of course I do." It's a notable broadside from a senator with nothing left to lose. And that's exactly the part worth paying attention to.
As reported by The Hill, Tillis's complaint centers on what he sees as Miller's influence over Cabinet operations and his preference for optics over execution. Miller, a longtime adviser to Trump dating back to his first presidential campaign, currently serves as deputy chief of staff.
Tillis laid out his case plainly:
"Not only does Stephen really want to just paint a picture. He's not worried about substance. He's more worried about form."
He went further, arguing that Miller's role has ballooned beyond what any staffer's should be:
"But I also think that he has an outsized influence over the operations of the Cabinet."
"And I believe we have got qualified Cabinet members there that sometimes are doing less than what they want to because of his direction and his outsized influence."
Tillis also pointed to the fatal shootings of Renee Good and Alex Pretti, two U.S. citizens shot by federal immigration officers in Minneapolis earlier this year, criticizing both Miller and DHS Secretary Kristi Noem for asserting that Good and Pretti were acting unlawfully. He further criticized Miller for pushing to increase immigration arrests.
Here's what deserves scrutiny: Tillis is retiring. He will never face another Republican primary voter. He will never need to answer to the base again. That changes the calculus of everything a politician says, and it should change how seriously we take the performance.
Washington is full of Republicans who discover their "independence" the moment they no longer need the electorate's approval. It's the cheapest form of courage available. The question isn't whether Tillis believes what he's saying. It's whether he would say it if his name were on a ballot in 2026.
The substance of the criticism, that a White House staffer exercises too much influence over Cabinet secretaries, is a legitimate governance concern that any conservative could raise in good faith. But the venue matters. CNN's "State of the Union" is not where you go to sharpen internal strategy. It's where you go to give the opposition ammunition dressed up as principled dissent.
If Miller's influence is truly undermining qualified Cabinet officials, the conversation belongs in the Oval Office, in private counsel with the president, or through Senate oversight mechanisms. Handing it to Jake Tapper on a Sunday morning guarantees it becomes a weapon wielded by people who don't want Trump's deportation agenda to succeed at all, not just want it executed differently.
The backdrop to all of this is a leadership change at the Department of Homeland Security. Secretary Kristi Noem will soon depart her Cabinet-level post, and Sen. Markwayne Mullin of Oklahoma is preparing for confirmation hearings to replace her.
On Mullin, Tillis struck a markedly different tone. He expressed confidence in the Oklahoma senator and framed his expected tenure in terms conservatives should welcome:
"He will leverage law enforcement resources, expertise, people like [White House border czar] Tom Homan to get things right."
Tillis said Mullin's approach would be "independent" and "driven by data," adding:
"But I have a lot of confidence in my friend, and I'm looking forward to him getting this department under control."
He also offered a note of accountability: "And if he doesn't, we'd hold him accountable."
The contrast is instructive. Tillis frames Mullin as the competent executor who will work with Homan and rely on law enforcement expertise. The implicit argument is that Mullin can succeed where Noem struggled, but only if Miller's influence recedes. Whether that diagnosis is accurate or self-serving is a question only those inside the building can answer.
Every administration has internal tension between political advisers and Senate-confirmed officials. It's not new, and it's not unique to this White House. The question is always whether the staffer is executing the president's vision or substituting his own.
Tillis clearly believes it's the latter. Others in the Republican conference have not joined him publicly. That silence speaks as loudly as Tillis's words, just in the opposite direction.
For conservatives watching this play out, the important thing isn't the palace intrigue. It's the policy. Trump's immigration enforcement agenda remains the most consequential domestic priority of his administration. The question isn't who sits in which office. It's whether illegal immigrants are being removed, whether the border is being secured, and whether the federal government is executing the law as written.
Personnel debates matter when they affect outcomes. If Mullin's confirmation brings sharper execution at DHS, that's a win regardless of what prompted the change. If the transition becomes consumed by the kind of public infighting Tillis just escalated, it hands the left exactly what they want: a story about Republican dysfunction instead of a story about border security results.
Retiring senators get to say whatever they want. The rest of the party has to live with the consequences.
