Trump administration updates: Schumer continues to face calls for new leadership

Elon Musk left the Pentagon after 80 minutes, declining to discuss what was talked about in the meeting.

As he departed Defense Secretary Pete Hegseth's office, Musk was asked by reporters how the meeting went. He responded, "It's always a great meeting."

When they were outside the building, Hegseth and Mush shook hands and Musk was overhead to say, "If there's anything I can do to be helpful, I'd like to see you."

They both ignored questions about whether they had discussed China or if it was a classified briefing.

At the very end of the exchange, the New York Times journalist who reported Musk was set to be briefed on "top-secret" plans about China asked the defense secretary what he and Musk discussed. Hegseth said, "Why would I tell you?" as he walked back inside.

Elon Musk has arrived at the Pentagon. He was seen exiting a black car and making his way into the building.

Defense Secretary Pete Hegseth said Thursday that Musk was coming for "an informal meeting about innovation, efficiencies & smarter production. Gonna be great!"

The New York Times reported that Musk would be briefed on military plans for any potential war with China, though Hegseth and Trump have denied that. Chief Pentagon spokesperson Sean Parnell also blasted the New York Times report as “ridiculous” and “fake."

It’s now unclear if Musk will actually attend a meeting with the Joint Chiefs of Staff that, among its topics, was supposed to touch on China.

As the Trump administration continues to refuse to provide additional information about deportation flights of alleged Venezuelan gang members to other countries, another hearing is set for 2:30 p.m. ET to determine if the administration can invoke the Alien Enemies Act of 1798.

U.S. District Court Judge James Boasberg will also determine if his order blocking any deportations should be extended.
