(CNN) - Sarah Palin will be in Columbia, South Carolina on Friday to endorse state Rep. Nikki Haley for governor.
This will mark the former Alaska governor's first political visit to the early primary state. Jenny Sanford, ex-wife of current Republican Gov. Mark Sanford, will also campaign with Haley on Friday.
Gov. Sanford is term-limited and will leave office in January.
Haley is locked in a four-way Republican primary against Lt. Gov. Andre Bauer, state Attorney General Henry McMaster and U.S. Rep. Gresham Barrett.
"It is a tremendous honor to receive Governor Palin's endorsement," Haley said Thursday in a statement. "Sarah Palin has energized the conservative movement like few others in our generation."
Palin's endorsement of Haley puts her at odds with her running mate in the 2008 presidential election, Sen. John McCain, R-Arizona.
McCain has backed McMaster in the primary. McMaster chaired McCain's South Carolina campaign in 2008.
