Sen. Tillis says Stephen Miller should leave the White House, calls him 'out of his depth'

Sen. Thom Tillis told CNN on Sunday that White House deputy chief of staff Stephen Miller should be removed from President Trump's inner circle. The retiring North Carolina Republican didn't mince words when Jake Tapper asked whether Miller should be relieved of his duties.

"Oh, of course I do," Tillis said.

The senator called Miller "out of his depth" and "repeatedly responsible for embarrassments," framing his critique around what he described as Miller's preference for optics over substance. It's the kind of public rebuke that, coming from a Republican, guarantees wall-to-wall cable news coverage. And that's precisely the problem with it.

What Tillis Actually Said

Tillis laid out a specific theory of the problem on CNN's "State of the Union." In his telling, Miller has accumulated too much operational power over Cabinet agencies, sidelining qualified appointees in the process.

"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 the influence extends beyond messaging:

"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 had previously criticized both Miller and DHS Secretary Kristi Noem for asserting that Renee Good and Alex Pretti, two U.S. citizens fatally shot by federal immigration officers in Minneapolis earlier this year, "were acting unlawfully." That earlier episode clearly sharpened the senator's view that Miller's judgment creates more problems than it solves, as The Hill reports.

The Mullin Pivot

Tillis paired his criticism with praise for Sen. Markwayne Mullin, who is preparing for confirmation hearings to replace Noem at the helm of DHS. Where Miller draws suspicion, Mullin apparently draws confidence.

Tillis said Mullin "will be independent" and "driven by data" in carrying out the administration's deportation agenda. He predicted that the Oklahoma senator would draw on the right people to execute the mission effectively:

"He will leverage law enforcement resources, expertise, people like Tom Homan to get things right."

And Tillis offered something that sounded almost like a conditional endorsement:

"And if he doesn't, we'd hold him accountable."

"But I have a lot of confidence in my friend, and I'm looking forward to him getting this department under control."

The framing is deliberate. Tillis isn't attacking the deportation agenda itself. He's arguing the agenda deserves better execution than Miller can provide. It's a personnel critique dressed in policy language.

A Retiring Senator's Megaphone

Here's the context that matters: Tillis is retiring. He doesn't face voters again. That frees him to say things sitting senators won't, but it also removes the accountability that makes political criticism meaningful. It's easy to throw grenades on your way out the door.

There's a pattern among departing Republicans who suddenly discover their appetite for public disagreement with the administration. The media loves it because it feeds a narrative of internal fracture. CNN didn't book Tillis because they care about DHS management structure. They booked him because a Republican criticizing a Trump adviser is catnip for their audience.

Tillis is a longtime adviser on immigration policy, and his concerns about the Minneapolis shooting aftermath aren't baseless. When federal officers kill American citizens, the response from leadership matters enormously. Getting that wrong is a serious failure, and the instinct to assert that the victims "were acting unlawfully" before the facts are fully established is the kind of unforced error that hands ammunition to people who want to delegitimize enforcement altogether.

But airing that critique on CNN, in the most explosive terms possible, doesn't fix the problem. It gives the left a clip to loop for a week.

The Real Question

The immigration enforcement mission is too important to be undermined by sloppy execution or by friendly fire from within the party. Both things can be true at once. Miller has been a driving force behind immigration enforcement since the first Trump campaign, a longtime adviser whose influence reflects the president's own priorities. Tillis may be right that Cabinet secretaries need more operational latitude. He may be right that form has overtaken substance in certain decisions.

But the conservative movement doesn't benefit from public fratricide conducted on liberal networks for liberal audiences. If Tillis has concerns about personnel, the Senate has tools for that. Confirmation hearings exist. Oversight letters exist. Phone calls to the West Wing exist.

Mullin's confirmation process will be the real test. If he brings the independence and data-driven approach Tillis promises, the enforcement apparatus will be stronger for it. That outcome matters far more than any Sunday show moment.

Retiring senators get one last turn at the microphone. The question is always who they're really talking to.
