Trump ousts Waltz as national security adviser

US President Donald Trump has removed Mike Waltz from his post as national security adviser, and will nominate him as ambassador to the United Nations, reports BBC.

In a post on social media, Trump thanked Waltz for his work and said he would be temporarily replaced by Secretary of State Marco Rubio, who will continue as America's top diplomat.

Waltz had faced criticism for mistakenly adding a journalist to a chat group where sensitive military plans were discussed - a political embarrassment likely to feature during confirmation hearings for the UN post.

The former Florida congressman is the first senior member of the administration to leave the White House in Trump's second term.

Multiple sources told the network he was ousted because of the Signal situation and a perception in the White House that he did not properly vet National Security Council staff, among other reasons.

But the sources said Trump respects Waltz so he was given a soft landing and a high-profile new post.

However, the BBC spoke to several US officials - who wished to remain anonymous - and they suggested the Trump administration believed Waltz might struggle to be confirmed by the Senate, allowing the president to get rid of him completely without having to fire him.

Waltz has been under scrutiny since he acknowledged in March mistakenly adding the editor-in-chief of the Atlantic magazine, Jeffrey Goldberg, to a group chat on Signal with top US security officials.

Confidential plans for a military strike on Yemen's Houthis were discussed on the message chain, whose members included Waltz, Rubio and Defence Secretary Pete Hegseth._Agencies.
