US Ambassador to the United Nations Nikki Haley has resigned her appointment, according to multiple sources familiar with her decision.
A senior State Department official said Haley told her staff on Tuesday morning.
White House spokeswoman Sarah Sanders said Trump and Haley would meet in the Oval Office at 10:30 am (1430 GMT), while the president tweeted he would be making a “Big announcement with my friend Ambassador Nikki Haley.”
Haley’s resignation was reported by US media including CNN, Fox News and The New York Times — none of which gave a reason for her departure.
During her more than a year-and-a-half on the job, she has repeatedly spoken her mind, whether it’s going further on human rights than many of her administration colleagues or denouncing racism at home.
