Trump's UN Ambassador Nikki Haley resigns

President Donald Trump announced on Tuesday that US Ambassador to the United Nations Nikki Haley has resigned and will leave her post by the end of the year.
Sitting side-by-side in the Oval Office, Trump praised Haley as a "fantastic person" who has "done an incredible job" and said he would gladly welcome her back into his administration down the line.
"She's done a fantastic job and we've done a fantastic job together. We've solved a lot of problems and we're in the process of solving a lot of problems," Trump said.
"She told me probably six months ago, 'You know maybe at end of the year -- at the end of the two year period -- but by the end of the year I want to take a little time off, I want to take a break,'" he added.

However, a source familiar with the situation told CNN that Haley notified Trump about her decision last week and did not tell Secretary of State Mike Pompeo or White House national security adviser John Bolton.
Both Bolton and Pompeo were surprised by the announcement, a source familiar told CNN.
Officials inside the White House, who had little indication Haley was resigning on Tuesday, are questioning her timing.
