US president Donald Trump ousted his national security adviser Mike Waltz on Thursday and named Secretary of State Marco Rubio as his interim replacement in the first major shakeup of Trump's inner circle since he took office in January.
Trump, in a social media post, said he would nominate Waltz to be the next US ambassador to the United Nations, adding that "he has worked hard to put our nation's interests first."
