Politico has Andrew Breitbart's response to ABC releasing a letter dropping him from their coverage of the 2010 elections:

Andrew Breitbart on Tuesday lashed out at ABC News for dropping him from the network's election night coverage, saying ABC bowed to “left-wing pressure” from Media Matters and other organizations.

“This is about cowardice and caving in to what was an overwhelming onslaught by Media Matters, the Huffington Post, TalkingPointsMemo and Daily Kos,” Breitbart told POLITICO. “This is their bowing to left-wing pressure...They know they can do it at any time and ay place and ABC will bow to pressure.”
