(CNN) - What would Stephen Colbert want in a Charleston, South Carolina, bowling alley?
Votes for his sister, who is running for Congress.
The Comedy Central comedian stumped on Saturday for Elizabeth Colbert Busch, one of two Democratic candidates running for the U.S. House seat vacated by now-Sen. Tim Scott, a Republican appointed to fill the Senate spot that Jim DeMint left last month.
Also seeking the seat in the GOP-leaning district are 16 Republicans, the most recognizable among them being former Gov. Mark Sanford. A primary will be held in March ahead of the May special election.
Colbert - the comedian - signed books and mingled at the campaign event in his hometown, held at bowling spot The Alley Charleston.
The Colbert Busch campaign posted to Twitter photos of the event.
"We're going to raise money in a bowling alley because we're of the people," he told fellow television host Jimmy Fallon on Thursday. "You know, you've got to go to a bowling alley because that's where the people are."
Bowling is "one of the few sports that comes with a bar."
Colbert has previously teased his own bids for public office, but said in the interview he hoped his career didn't hurt his sister's chances.
"I don't actually have anything to offer people in a public office," he said. "It's natural for her to run because she has skills and something to offer society. I am professionally ridiculous. So I just hope that what I do for a living doesn't sully her good character."
