WASHINGTON- Nikki Haley, US ambassador to the United Nations, has resigned after being at the post for nearly two years.
Haley, 46, did not give any reason for her exit but dismissed speculation she was planning to run for president in 2020.
"It's been eight years of intense time, and I'm a believer in term limits," she said. "I don't have anything set on where I'm going to go.”
US President Donald Trump said, “she has been very special to me, she has done an incredible job, she is a fantastic person, very importantly, but she is also somebody that gets it".
"Hopefully you'll be coming back at some point, right," Mr Trump said. "Maybe a different capacity, you can have your pick."
Mr Trump will announce her replacement in two-three weeks. Former deputy Security Council adviser Dina Powell is being considered for the post.
