(CNN) - Rep. Gresham Barrett of South Carolina will officially announce Wednesday that he will run for governor of his home state, a spokesman confirmed to CNN.
Barrett will declare his intention to seek the Republican gubernatorial nomination in an email to supporters and in a video posted on his campaign Web site.
"I believe I have certain strengths in these uncertain times," Barrett writes in the email, according to an early excerpt provided to CNN. "And I believe we have to hold on to our conservative values, and change the things that hold us back… I am excited about this campaign, and honored to have the opportunity to share my vision for a more prosperous South Carolina with the hard-working people of our great state."
Barrett was first elected to Congress in 2002 and won re-election in 2006. Prior to that, he served in South Carolina's House of Representatives.
Current South Carolina Gov. Mark Sanford, also a Republican, is in his second term in office. Term limits prevent him from seeking a third term.
South Carolina's Attorney General Henry McMaster and Lieutenant Gov. Andre Bauer are also considering gubernatorial bids and are likely primary opponents to Barrett.
