CHARLESTON, South Carolina (Reuters) -Nikki Haley ended her long-shot challenge to Republican presidential frontrunner Donald Trump on Wednesday, ensuring the former president will be the party's candidate in a rematch with Democratic President Joe Biden in November's election.
Haley, the former South Carolina governor and Trump's ambassador to the United Nations, bowed out a day after Super Tuesday, when Trump beat her soundly in 14 of 15 Republican nominating contests.
