Media Matters shill Eric Alterman was arrested tonight at the Democratic debate: CNN Political Ticker Columnist/author arrested in spin room.

Goffstown, N.H. police say Alterman was in the spin room as a guest of the Creative Coalition and went to an area reserved for a private reception for WMUR-TV. Police say he was asked by an executive at the party if he was invited to the private area and was asked to leave. A police officer was called after a verbal altercation ensued. He was asked by police seven times to leave, and police say he became increasingly loud as he refused. After ignoring a final request, police say he was handcuffed and taken from the building. He is charged with criminal trespass, and a bail commissioner will determine if he will be released.
