Bill Maher: 'fact check MSNBC and they are very rarely wrong

HBO "Real Time's" Bill Maher appeared on CNN's "Piers Morgan Live" Tuesday night to talk politics and the media. He specifically compared MSNBC to Fox News.

"The difference between Fox and MSNBC is you can fact check what they say on MSNBC and they are very rarely wrong," Maher said. "They are not flying in the face of facts. Fact check what they say on Fox and you will find almost every night Bill O'Reilly says something that is insanely off base and not true."
