Mike Waltz, President Donald Trump's national security adviser, is set to leave his White House post amid continued fallout weeks after he invited a journalist into a chat between top national security officials discussing plans for Yemen airstrikes.
A source familiar with the situation on May 1 confirmed Waltz's exit, as well as deputy national security adviser Alex Wong. Their departures mark the first major staff shake-up since Trump's return to the White House in January.
Trump had publicly stood by Waltz after his national security adviser and other members of the chat vigorously denied sharing any classified war plans on the publicly available app Signal. The chat was revealed when Jeffrey Goldberg, the editor-in-chief of The Atlantic, published a March 24 story detailing how Waltz accidentally invited him into the communications.
