U.S. National Security Adviser Mike Waltz and his deputy Alex Wong will leave their posts at the White House, CBS News reported, citing multiple sources.

They are expected to leave their posts on Thursday. Waltz came under scrutiny in March after he hosted a Signal chat room and mistakenly included journalistJeffrey Goldberg of The Atlantic in it, describing talks with top national security officials about plans for a military strike against Houthi targets in Yemen.

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

After Waltz acknowledged the authenticity of the report behind closed doors, White House officials discussed whether he should resign, but Waltz never made such an offer, and U.S. President Donald Trump did not ask him to resign at the time.

Wong, in turn, served in the first Trump administration as deputy special representative for North Korea and deputy assistant secretary of state for East Asian and Pacific affairs at the State Department.

In announcing his appointment, Trump said Wong helped him negotiate high-level talks with North Korean leader Kim Jong Un.
