Outgoing U.S. Ambassador to the United Nations Nikki Haley on Tuesday dismissed speculation she is open to challenging President Trump for the Republican presidential nomination in 2020.

“For all of you that are going to ask about 2020, no, I am not running for 2020. I can promise you what I’ll be doing is campaigning for this one,” Haley told reporters gathered in the Oval Office. “I look forward to supporting the president in the next election.”
