COLUMBIA — Greenville businessman John Warren is getting a major boost in his quest to unseat Gov. Henry McMaster in the Republican campaign for governor, with endorsements from two other candidates.

Warren's campaign tells The Associated Press that he's getting endorsed Thursday by Lt. Gov. Kevin Bryant and former public health chief Catherine Templeton.

McMaster got only 42 percent of Tuesday's GOP primary vote, forcing a runoff. Warren, Templeton and Bryant received a combined 56 percent. Warren finished second, and is hoping his rivals' backing could push him over the top.

Both Templeton and Warren ran as "outsiders" without experience in elected politics, saying it's time for a new generation to lead the state. Templeton ran two state agencies in Gov. Nikki Haley's administration, while Warren, who served in the Marines and founded a Greenville mortgage company, had never been involved in politics at all.

Templeton told the AP in an interview that Warren is the right candidate to carry on the messages she had shared in her campaign.

"John is the future, and Henry is the past," she said. "I sat with John and asked all the hard questions. He will build a team of experts to help him drain the swamp, and I am proud to trust my money and my children with him as our next governor."

The campaign planned a series of joint events throughout the day, starting in Columbia.

McMaster and Warren will debate next week in Newberry ahead of the June 26 runoff. The winner faces Democratic Rep. James Smith in November.
