Nikki Haley abruptly resigned Tuesday as the US ambassador to the United Nations, in the latest departure from President Donald Trump's often shifting national security team.
Meeting Haley in the Oval Office, Trump said she had done a "fantastic job" and would stay on to the end of the year.
"She told me probably six months ago," Trump told reporters, that '"I want to take a little time off.'"
A successor will be named "in the next two or three weeks," he said.
