Uh-oh. Looks like Stephen hurt Bill O's feelings. O'Reilly slammed Colbert earlier this week, calling him a "vacant" ideologue who doesn't know what he's talking about. (In other news, Bill has never heard about the pot calling the kettle black.)
Check out Colbert's response to Bill after the jump.
Stephen also looked at the protests in Hong Kong with The People's Republic of Amnesia author Louisa Lim.
Stephen's guest last night was former Chairman of the Joint Chiefs of Staff Mike Mullen.
