Sanders, an independent who aligns himself with Democrats, called MSNBC's decision to suspend Olbermann, who admitted to making donations to several Democratic candidates this cycle, "outrageous."

“It is outrageous that General Electric/MSNBC would suspend Keith Olbermann for exercising his constitutional rights to contribute to a candidate of his choice," Sanders said, referring to the network's corporate parent. "This is a real threat to political discourse in America and will have a chilling impact on every commentator for MSNBC."

Olbermann admitted to making the maximum donations to three Democrats: Reps. Raúl Grijalva (D-N.M.) and Gabrielle Giffords (D-Ariz.) and Kentucky Democratic Senate candidate Jack Conway.

MSNBC President Phil Griffin announced Olbermann's indefinite suspension without pay on Friday.

Sanders said that MSNBC had been particularly unfair to Olbermann considering the conservative bias the Vermont senator alleged of Fox News and "90 percent of talk radio."

“Is Rachel Maddow or Ed Schultz next? Is this simply a ‘personality conflict’ within MSNBC or is one of America’s major corporations cracking down on a viewpoint they may not like?" he said. "Whatever the answer may be, Keith Olbermann should be reinstated immediately and allowed to present his point of view.”
