GOP presidential candidate Jeb Bush says he is "disappointed" that South Carolina Gov. Nikki Haley is endorsing rival Marco Rubio just three days before voters in the state cast ballots for the Republican nominee.
Speaking to reporters after a campaign event in Summerville, S.C., Bush said of Haley: "She's a very good governor and should I win the nomination, there'll be a role for her in the campaign."
Haley's endorsement of Rubio was confirmed by a person close to the Republican governor with direct knowledge of her decision. The person was not authorized to publicly discuss the endorsement ahead of a Rubio event Wednesday night, where she's expected to make it official.
Bush has struggled to keep his campaign afloat, calling in help from brother George W. Bush, the former president, and his mother, Barbara Bush. Jeb Bush's brother and father won big primaries in the state in 2000 and 1988.
