President Donald Trump has gone through his share of national security advisers. But he doesn't hold the record, yet.

National security adviser Mike Waltz is leaving his White House post, although soon after reports about his departure were published, President Trump announced he plans to nominate him to be ambassador to the United Nations.

President Trump removed Mike Waltz as national security adviser because the Floridian would be a “better UN ambassador,” Vice President JD Vance said Thursday — arguing that the former congressman’s nomination to rep the US in Turtle Bay could be considered a “promotion.”
