President Donald Trump vowed Friday to fire Federal Reserve Board Governor Lisa Cook if she doesn't resign.

The comments come after Trump's Federal Housing Finance Agency head Bill Pulte accused Cook of committing mortgage fraud. Pulte referred Cook, the first Black woman to serve on the Federal Reserve Board of Governors, for criminal prosecution, but she has not been charged.

"What she did was… bad so I'll fire her if she doesn't resign," Trump said, without giving more details about the allegations against Cook.

Cook pushed back on the calls for her to step down in a statement released Wednesday.

"I have no intention of being bullied to step down from my position because of some questions raised in a tweet. I do intend to take any questions about my financial history seriously as a member of the Federal Reserve and so I am gathering the accurate information to answer any legitimate questions and provide the facts," she said.

Trump didn’t offer any updates Friday on timing for a potential meeting between himself, Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy when asked if there was any movement on the possibility of one.

Trump said he would "rather not" have to be in the meeting, but that he would "have to be there" because Putin and Zelenskyy, "don’t get along too well, for obvious reasons."

“We’ll see. We're going to see if Putin and Zelenskyy will be working together,” Trump said about progress.

“It’s like oil and vinegar a little bit, they don't get along too well, for obvious reasons, but we'll see," he added.

President Donald Trump has weighed in for the first time on the FBI search of John Bolton's home on Friday morning, saying he knows "nothing about it."

"I don't know about it. I saw it on television this morning," Trump said. "I'm not a fan of John Bolton; he's a real sort of a lowlife."

Asked if the Department of Justice will brief him on the search, Trump told reporters: "They'll brief me, probably today sometime."

"I don't wanna -- I tell [Attorney General Pam Bondi] and I tell the group, 'I don't wanna know about it. Just, you have to do what you have to do.' I don't wanna know about it. It's not necessary. I could know about it. I could be the one starting it. I'm actually the chief law enforcement officer. But I feel that it's better this way," Trump continued.

President Donald Trump on Friday morning took a surprise trip to "The People's House" -- a museum about the White House and its inhabitants.

Trump took reporter questions after the tour on the FBI search of John Bolton's house, the Russia-Ukraine war, the federal takeover of Washington and more.

Trump said his next stop this morning will be the Kennedy Center.
