MSNBC’s David Shuster has been suspended for the following:

DAVID SHUSTER: Bill, there's just something a little bit unseemly to me that Chelsea's out there calling up celebrities, saying support my mom, and she's apparently also calling these super delegates.

BILL PRESS: Hey, she's working for her mom. What's unseemly about that? During the last campaign, the Bush twins were out working for their dad. I think it's great, I think she's grown up in a political family, she's got politics in her blood, she loves her mom, she thinks she'd make a great president --

SHUSTER: But doesn't it seem like Chelsea's sort of being pimped out in some weird sort of way?

Can you tell me what he is being suspended for?
