US National Security Advisor Michael Waltz will exit his post, CBS News first reported, and will be nominated to be ambassador to the United Nations. It brings a premature end to the Floridian’s tumultuous White House stint, one that has been marred ever since he accidentally added a journalist from The Atlantic to a Signal chat regarding US attack plans in Yemen. US Secretary of State Marco Rubio will replace Waltz, holding his role on an acting basis.

Waltz out of step. Though the former congressman wasn’t the one who shared war plans on the chat – US Defense Sec. Pete Hegseth holds that honor – he ultimately took responsibility. President Donald Trump initially seemed willing to give Waltz a second chance, but it turned out that the national security adviser had created several other Signal chats to discuss foreign policy.

The original Signal faux-pas also raised questions over the exact nature of Waltz’s relationship with The Atlantic Editor-in-Chief Jeffrey Goldberg. Neither Waltz nor Goldberg would comment on it.

History repeats itself. Trump fired former National Security Adviser Michael Flynn just 22 days into his first term. The president reportedly regretted this decision, so was reluctant to remove Waltz this time, and instead landed on a reshuffle.

Hegseth gets away with it – for now. The former Fox News host seems to have escaped punishment, even though it emerged that he also shared war plans with his wife, brother, and lawyer in a separate Signal chat. A former Pentagon spokesperson also said the Department of Defense has been in “total chaos” under his leadership. Trump has thus far backed Hegseth, although he hedged on whether he had full confidence in him during an ABC News interview that aired on Tuesday.

A full plate for Rubio. The former Florida senator entered the administration as the secretary of state, but he now counts USAID administrator and the acting National Security role in his portfolio. Whether he lasts in this trio of roles for long is another matter — the Miami native has long had presidential ambitions, which he could pursue in 2028.
