BREAKING: Mike Waltz out as National Security Advisor: report

The Trump administration's National Security Advisor Mike Waltz is out from his role along with other staff, according to reporting from Fox News.

The outlet confirmed with sources that on Thursday, Waltz, as well as his deputy Alex Wong, were removed from their positions. The removal follows Waltz coming under fire when Atlantic editor-in-chief Jeffrey Goldberg was added to a Signal chat with others in the administration, in which plans to attack the Houthis were discussed.

Fox reported that the removal of other staffers will likely be announced, and Trump is expected to make comments on the matter. Waltz previously served as a Green Beret and was elected to Congress from Florida's 6th district.

When the Signal chat controversy occurred, Waltz took responsibility for the fluke, and said, "I take full responsibility. I built the group," while speaking to Laura Ingrahm. "It's embarrassing. We're going to get to the bottom of it."

Leading up to the firing, there were reports that the Trump administration considered ousting him from the position. When White House Press Secretary Karoline Leavitt was asked about the reports, she said that the president was not "going to respond to reporting from anonymous sources."

Wong had served as the principal deputy national security advisor for Walz and was the person appointed to pull "together a tiger team" in a message sent to the Signal chat earlier this year.

"Team – establishing a principles [sic] group for coordination on Houthis, particularly for over the next 72 hours," Waltz wrote in the Signal chat. "My deputy Alex Wong is pulling together a tiger team at deputies/agency Chief of Staff level following up from the meeting in the Sit Room this morning for action items and will be sending that out later this evening."

When the news of the chat being shared with Goldberg broke, Trump said on April 3 that some of the staffers at Waltz's office had been let go.
