U.S. Ambassador to the United Nations Nikki Haley has resigned from her top diplomatic post.
President Trump accepted the former South Carolina governor's resignation after the pair discussed her departure during a White House visit last week, Axios first reported Tuesday. The timing of when she will officially leave the role is still unclear.
White House press secretary Sarah Sanders announced on Twitter that Trump and Haley will meet in the Oval Office at 10:30 a.m. ET in a meeting that will be open to news outlets. Trump tweeted soon after he and his "friend" Haley would have a "big announcement."
American Conservative Union chair Matt Schlapp, whose wife Mercedes Schlapp is White House director of strategic communications, said on Fox News after the news broke: "Unless this is a personal issue or health concern, which I hope is not the case, it's obviously very unusual for a significant and prominent person on the president's team to announce that she is leaving so close to an election. There is something to this story. Like everyone in America I want to know what it is."
