Washington DC - Republican Senator Thom Tillis recently revealed that he has some regrets over his vote to confirm Pete Hegseth as President Donald Trump's defense secretary.

On Wednesday, the North Carolina lawmaker sat down for an interview with CNN, during which he argued that Hegseth appears to be unqualified for the role.

"With the passing of time, I think it's clear [Hegseth is] out of his depth as a manager of a large, complex organization," Tillis said.

While Tillis said he did not exactly regret casting the vote based on what he knew at the time, he now has "the information of him being a manager, and I don't think that his probationary period's been very positive."

Tillis went on to point out how Hegseth last week failed to give the White House notice before he authorized a pause on weapon shipments to Ukraine for their ongoing conflict with Russia. It was the second time he failed to do so since being appointed.

"That's just amateurish," he said. "That's from somebody who doesn't understand large organization dynamics."

Tillis also expressed disappointment in other Trump cabinet members, such as Health Secretary Robert F. Kennedy Jr., explaining that while he has no problem with the president specifically, "I got a problem with some of the people I consider to be amateurs, advising him."

Tillis' remarks came after he gained the ire of Trump by vowing to oppose the controversial "Big, Beautiful Bill," which ended up passing in both the Senate and House recently.

In response to Tillis' opposition, Trump threatened to back a primary challenger to unseat him, which led to Tillis announcing last month that he would not be seeking re-election.

In the interview, Tillis evaded criticizing Trump directly and instead said of his advisors, "I want to make it very clear to them: When you act like the president when he's out of the room, you don't impress me."
