Trump admin updates: Trump says tariff letters to be sent to 'various countries' on Monday

Trump said he didn’t cut any deals with House holdouts to get his tax and spending bill passed.

“No deals. No deals. What I did is -- we talked about how good the bill is. I mean, that's a deal, I guess, when you think about it but, obviously, convince them, but it was not hard,” he said. “This is a great bill. This is going to be a great bill for the country.”

Rep. Ralph Norman, one of the holdouts, said earlier Thursday that Trump promised to “make the bill better” in the future when he told him about his concerns that not enough was being cut.

Asked about what it says about the power he’s amassed to get his megabill over the finish line, Trump said he believes he has more power now than ever before.

"I think I have more power now," Trump said as he headed for an event in Iowa Thursday afternoon. "I do, you know, I could say, 'Oh, gee, I don't know.' I think I probably do, because we've had a great record of success."

"You know, my first term was very, very successful. We had the greatest economy in the history of our country. I think we're going to blow it away this term,” Trump claimed.

"But, you know, we've, we've proven certain things. And, yeah, I think probably it's got more gravitas, more power," he added.

Relevant congressional leaders were not informed of the Pentagon's decision to pause some munitions intended for Ukraine, two congressional sources told ABC News.

Members of Congress found out in the media and the paused shipments were obligated using funds and authorities granted by Congress, the sources said.

Top Democratic appropriators for defense called the move the "most dramatic blow to our support for Ukraine" in a statement, adding the aid was "designated to be delivered months ago."

“The Pentagon’s reported cancellation of already-promised weapons shipments to Ukraine risks the lives of the brave Ukrainian men and women on the front lines of freedom and rewards President Putin and his Russian forces," Sens. Jack Reed, D-R.I., and Chris Coons, D-Del., said. "This assistance -- including vital air defense interceptors and artillery munitions -- was provided by Congress and designated to be delivered months ago."

"President Trump has a critical opportunity to actually achieve peace through strength: to improve Ukraine’s leverage and force Putin to negotiate," the senators said.

President Trump on Thursday spoke with reporters and reiterated his appreciation to Republicans who voted in favor of the bill.

"Great for security, great on the southern border. Immigration is covered. We covered just about everything. Again, it's the biggest bill ever signed of its kind," he said.

Trump claimed he didn't have a problem negotiating with the holdouts in the end.

"No deals. What I did is we talked about how good the bill is. I mean, that's a deal, I guess, when you think about it," he said.

Trump also thanked Senate Majority Leader John Thune and House Speaker Mike Johnson for their work.
