State Department spokesman Tammy Bruce found out about the change of Mike Waltz's work from a reporter during a press briefing.
US President Donald Trump has published on Truth Social that he will designate a waltz as “the next United States Ambassador in the United Nations organization.”
Continuing his post, Trump added that Secretary of State Marco Rubio would also serve as a national security adviser in the meantime.
It is coming after the reports said that Valtz would withdraw from his role as a national security advisor.
