National Guard troops in DC are now armed, defense official says

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.

In a 5-4 decision, the Supreme Court allowed the Trump administration to cancel more than $780 million in research funding from the National Institutes of Health.

The Trump administration sought to cut the funds saying they advanced “gender ideology extremism” and diversity, equity, and inclusion efforts.

In a splintered ruling, the majority continued to block the Trump administration’s anti-DEI directive on future funding decisions. Chief Justice John Roberts sided with the court’s three liberals who would have blocked the funding cuts.

In a lengthy dissent, Justice Ketanji Brown Jackson criticized her colleagues for overusing the high court’s emergency appeals process.

“Stated simply: With potentially life-saving scientific advancements on the line, the Court turns a nearly century-old statute aimed at remedying unreasoned agency decisionmaking into a gauntlet rather than a refuge,” she wrote.

Administration officials claim the terminated studies fulfill the president's executive order to root out "DEI" initiatives across government.

Public health groups, backed by the ACLU, insist they are critical projects that have undergone rigorous peer review.

A district court determined the cancellations were "arbitrary and capricious, and unlawful" and put them on hold pending the outcome of litigation.

Canadian Prime Minister Mark Carney spoke with President Donald Trump on Thursday, according to representatives from both leaders.

Carney "had a productive and wide-ranging conversation" with Trump where they "discussed current trade challenges, opportunities, and shared priorities in a new economic and security relationship between Canada and the U.S.," according to Canadian officials.

"The leaders also discussed how to build on the President’s leadership to support long-term peace and security for Ukraine and Europe," the officials added.
