Trump 2nd term updates: Trump says USAID is run by 'radical lunatics'

White House press secretary Karoline Leavitt brushed off Elon Musk's comment suggesting investors don't have the money to fund the Stargate AI project during an interview on Fox News.

"President Trump is very excited about this infrastructure announcement in the field of AI, which is of his growing United States and it needs to capitalize on it because adversaries like China are very advanced in the field," Leavitt dodged when asked for the Trump's reaction specifically to Musk's comments.

Musk has repeatedly poured cold water on the $500 billion project, which Trump rolled out at the White House on Tuesday evening with fanfare.

Leavitt said that the American people should trust Trump at his word.

"So, the American people should take President Trump and the CEOs' words for it. These investments are coming to our great country and American jobs are coming with them," she said.

Enrique Tarrio, the former head of the Proud Boys, arrived in Florida one day after being freed from prison following Trump's sweeping Jan. 6 pardons.

He was seen embracing supporters at Miami International Airport.

Tarrio was sentenced to 22 years for his conviction on seditious conspiracy. He'd received the longest sentence of all the convicted Jan. 6 rioters, though he was not at the Capitol that day.

In a clip previewing his first sit-down interview since becoming president, Trump criticized Joe Biden’s preemptive pardons before he left the White House.

“Joe Biden ran and said he would never do preemptive pardons. It was an issue that came up when you were leaving your first time...” Fox News' Sean Hannity began before Trump jumped in.

"Oh, he heard that I was going to do it, I didn't want to do it. I was given the option, they said, 'Sir, would you like to pardon everyone -- including yourself?’ I said 'I'm not going to pardon anybody. We didn't do anything wrong.' We had people that suffered. They're incredible patriots. We had people that suffered. You had Bannon put in jail. You had Peter Navarro put in jail. You had people that suffered and far worse than that, they lost their fortunes and whatever their nest egg paying it to lawyers," Trump said.

"And those people -- people said -- they wouldn't have even taken, most of those people, they wouldn't have even taken a pardon. This guy went around giving everyone pardons. And the funny thing, maybe the sad thing, is he didn't give himself a pardon -- and if you look at it, it all had to do with him," Trump added.

The full interview is scheduled to air at 9 p.m. ET on Fox News.

President Trump is sending 1,500 additional troops to the southern border, building off the executive actions he signed on Monday, White House press secretary Karoline Leavitt announced to reporters.

"This is something President Trump campaigned on. The American people have been waiting for such a time as this for our Department of Defense to actually take homeland security seriously. This is the number one priority of the American people and the president is already delivering on that," she said.

"Securing the southern border and deporting illegal immigrants from this country. President Trump is sending a very strong message to people around this world: if you are thinking about breaking the laws of the United States of America you will be returned home, you will be arrested you will be prosecuted. Do not come," she told ABC News Chief White House Correspondent Mary Bruce when asked what the troops will be doing and what their mission is.
