Sen. Thom Tillis (R-NC) ripped President Donald Trump's White House on Friday over his targeting of blue states.

Budget chief Russ Vought aggressively targeted blue states last year over Trump. The Trump administration suspended or canceled billions in federal funding for infrastructure and energy projects, including freezing $18 billion in transit and tunnel projects in New York City, withholding about $2 billion for Chicago rail improvements, and eliminating nearly $8 billion in Department of Energy funding for clean energy initiatives across 16 states that voted Democratic in the 2024 election.

Tillis warned Vought could hinder Republican efforts to end the government shutdown, The Daily Beast reported.

“I think that digs us a deeper hole. I think if you do that, you’re going to create a bad faith environment here that could put us further out,” Tillis said.

Tillis said the administration needs to be "very judicious" and should be "consulting with Senate leadership and House leadership before they do it."

"If they do it on their own, then they can own some of the reason why we get to an impasse," he said flatly.

Tillis warned that if Vought's office cancels programs "foundational to past compromises, you destroy the credibility of future compromises."

"Quite honestly, if I’m a Democrat, and I negotiated something... and I’ve been tracking that program and it gets tanked, I’m not going to have any faith that you can deliver on your promises in this administration. That’s just the reality,” he declared.

Tillis, who has publicly broken with Trump, announced over the summer his plans to retire from the Senate. He has said he planned to use his position to be a thorn in the president's side and bring down certain Trump aides he derided as "amateurs."
