National security adviser Mike Waltz and his deputy, Alex Wong, will be leaving their posts in the Trump administration weeks after the Signal leak scandal, according to US broadcasting network CBS. Mr Waltz, serving as National Security Advisor, became embroiled in the controversy after inadvertently adding journalist Jeffrey Goldberg to a Signal group chat discussing sensitive US military operations in Yemen.

The chat included high-ranking officials such as Defense Secretary Pete Hegseth and Vice President JD Vance, and contained detailed operational plans. Waltz publicly took full responsibility for the mishap, acknowledging the error as "embarrassing". The incident sparked bipartisan criticism, with some lawmakers calling for Mr Waltz's resignation and raising concerns about the use of unsecured communication platforms for classified information.

Speaking at the time, Mr Waltz said: "I take full responsibility. I built the group."

"We've got the best technical minds looking at how this happened."

"I can tell you for 100% I don't know this guy."

Asked how Mr Goldberg's details had been added, he said: "Well, if you have somebody else's contact, then somehow it … gets sucked in. It gets sucked in."

President Donald Trump, however, initially defended Mr Waltz, suggesting that the issue stemmed from technological imperfections rather than misconduct .​

He described it "the only glitch in two months" of his administration, adding: "Michael Waltz has learned a lesson, and he's a good man."

If the reports are accurate, Mr Waltz will by far the highest profile Trump appointee to leave his job so far since the billionaire returned to the White House in January.
