Stephen Colbert: 'Why wasn't I mentioned in 'Game Change'?'

Author Mark Heilmann sat down with Comedy Central's Stephen Colbert Wednesday, to talk about his best-selling book, "Game Change," which he co-authored with Mark Halperin.

Colbert's character, a conservative megalomaniac, ribbed Heilmann for the book's use of anonymous sources to make personal allegations, and he complained that he wasn't included in the book, which chronicles the 2008 presidential campaign.

"I ran for president and I'm not in your book," said Colbert, referring to his 2007 attempt to get on the ballot in his home state of South Carolina (his request was rejected, citing worries about his "seriousness").

Heilmann told Cobert that he and Halperin wrote an entire chapter about Colbert's short-lived bid, but it was rejected by publishers due to space constraints. The book is 464 pages.
