National security adviser Mike Waltz and his deputy, Alex Wong, will be leaving their posts in the Trump White House, according to multiple sources familiar with their departure.

In March, Waltz came under scrutiny after he put together a Signal chat and mistakenly included The Atlantic’s Jeffrey Goldberg, disclosing discussions with top national security officials about plans for a military strike on Houthi targets in Yemen.

Goldberg published his account, and he initially omitted operational details, but after Defense Secretary Pete Hegseth, Director of National Intelligence Tulsi Gabbard and CIA Director John Ratcliffe denied any classified information had been shared on the chat, Goldberg published that information, too, which included the timing of the strikes and the weapons packages used.
