Nikki Haley plans to launch White House bid Feb. 15

Nikki Haley is moving closer to making her presidential campaign official. Haley, 51, served as South Carolina's governor for six years before serving as President Donald Trump's ambassador to the United Nations.

On Wednesday, supporters of the former South Carolina governor will get an email invitation to a Feb. 15 launch event in Charleston, at which she plans to announce her campaign. When she enters the race, Haley will be the first contender to join the contest against her former boss, who is currently the sole Republican seeking his party's 2024 nomination.
