House Speaker Mike Johnson texted Elon Musk in the last hour, urging him to keep up his work with DOGE and telling him to "continue the effort, because it's really important for us to get to restore fiscal sanity."

When asked if he's comfortable with Elon Musk's role and access to federal agencies, Johnson emphasized the "very important service for the people" that Musk is doing, and that he is "encouraging him to continue digging."

Johnson also said "it's not that simple" when asked if Trump has the authority to shut down government agencies without Congress, adding that it "all depends on the details."

"If they're executive branch agencies, the executive is in charge of them. Congress funds them. But there are important, you know, questions to be asked about all the parameters of that. So, I don't have all the -- it's not an easy answer," Johnson said.

In regards to USAID, Johnson said, "there have been a lot of abuses in that agency" and said there will be "an appropriate action," though he added that they "haven't yet sorted out exactly what's happening with it" and he would not say whether the executive order to dismantle USAID violates the constitution.

President Donald Trump pushed back on criticism against the qualifications of some of Musk’s DOGE team, who are reportedly as young as 19 years old, saying, "That’s good."

The president said he hadn't seen any of those employees but claimed they worked out of the White House.

"They're smart people, unlike what they do in the control towers, where we need smart people. We should use some of them in the control towers," he said before making a reference to his baseless claims about air traffic control tower employees.

President Donald Trump, who signed an EO that took aim at Iran, was asked about the threats the nation has made against him.

The president said they "would be obliterated" if they did that.

"I've left instructions. If they do it, they get obliterated. There won't be anything left, and they shouldn't be able to do it," he said.

"I can't imagine they do that," Trump later added.

California Gov. Gavin Newsom will travel to Washington, D.C., to meet with Trump administration officials and members of Congress, his office said.

"The governor's trip is focused on securing critical disaster aid for the survivors of the Los Angeles fires and ensuring impacted families who lost their homes and livelihoods have the support they need to rebuild and recover," his office said in a statement.
