Stephen Colbert, the comedian, and Elizabeth Colbert Busch, the South Carolina congressional candidate, will be rolling through D.C. later this month, as the "Colbert Report" host once again plans to be a fundraising attraction for his political sister. Both Colberts will be in D.C. on April 15 for the event, being held at B. Smith's in Union Station. Tickets for the fundraiser aren't cheap, starting out at $500 for general admission and going up to $10,000 to be named an event chair.
