Breaking: MSNBC's David Shuster Suspended 'Indefinitely'

Update - 10:45 AM | Lachlan Markay: Contessa Brewer is filling in for Shuster during his 10 am slot. Mediaite is reporting that Ed Schultz will take the 3 pm slot. This will not be the permanent lineup, however.

MSNBC's David Shuster was suspended indefinitely today after a flap with the cable network's brass, who were livid that he filmed a pilot for CNN. Shuster, whose contract is set to expire at the end of the year, has not appeared on air since the news broke.

"If true," said MSNBC spokesman Jeremy Ganes after hearing the news, "this is unacceptable and David will be punished appropriately." MSNBC President Phil Griffin was vacationing in Florida, but reportedly "ripped Shuster a new one over the phone," according to Gail Shister of TV Newser.

This morning MSNBC announced that Shuster has been suspended "indefinitely." Anything less than suspension, an MSNBC exec told Shister, "sends a message from management that this is OK."

Shuster was also suspended in 2008 after he said that Hillary Clinton had "pimped out" her daughter Chelsea. He was repremanded in January for inappropriate comments made on his Twitter feed directed at conservative journalist James O'Keefe.
