After he lost the gubernatorial runoff in June, South Carolina Rep. Gresham Barrett said he would support fellow Republican Nikki Haley for governor. He apparently meant what he said.

The four-term congressman is listed as one of the "special guests" at a Washington fundraiser for Haley set for Sept. 22. The rest of the South Carolina GOP delegation is also attending the event, according to an invite. But Barrett's inclusion is notable because he faced Haley in the hard-fought primary and subsequent runoff.

The event is being billed as a "rooftop reception" at the offices of Nelson Mullins, a law firm with a substantial presence in the Southeast. Tickets range from $1,000 to $3,500. Haley is also set to attend a low-dollar fundraiser at a Capitol Hill Mexican restaurant that will feature Sen. Scott Brown (R-Mass.). 

Haley, the first female GOP gubernatorial nominee in the state's history, faces Democrat Vincent Sheheen in the race to succeed the term-limited Gov. Mark Sanford (R).
