Former Gov. Mark Sanford's campaign announced its first post-primary endorsement Wednesday by Elizabeth Moffly, a Charleston County school board member and unsuccessful candidate in Tuesday's GOP primary.

"Mark is a proven leader with an incredible record of cutting spending and eliminating waste," Moffly said in a statement. "I believe he will represent the first district as an ardent taxpayer watchdog, and I look forward to helping him win this runoff and the upcoming general election."

Sanford faces Charleston attorney Curtis Bostic in a runoff April 2.
