WASHINGTON - Vice President Joe Biden will campaign in South Carolina for Democratic congressional candidate Elizabeth Colbert Busch, a White House official confirmed to CNN.
Colbert Busch won the Democratic nomination for the vacant 1st Congressional District seat this past week.
Biden will head to South Carolina the weekend before the May 7 general election, the official said.
Colbert Busch, who is the sister of comedian Stephen Colbert, will face either former congressman and governor Mark Sanford or former Charleston County Councilman Curtis Bostic for the House seat. The two Republicans face off in an April 2 runoff to determine the GOP nominee.
Colbert, a satirist and host of a Comedy Central show, campaigned on his sister's behalf.
"She's my sister, and I'm willing to, you know, break the jewel of my own creation to try to do something for her," Colbert told CNN Chief Washington Correspondent Jake Tapper this week on CNN's "The Lead."
Colbert Busch, an official with Clemson University's wind turbine drive testing facility, is expected to have an uphill climb because the district is heavily Republican and one in which Mitt Romney won by a larger margin than he did in the state as a whole.
A South Carolina political newsletter first reported Biden's upcoming appearance.
