A Clinton campaign official calls the comment "beneath contempt" and disgusting. And he says it could threaten Clinton's participation in a debate later this month on MSNBC, and in future debates on the network.
Shuster apologized on the air for the comment. And an MSNBC spokesman says the network offers its "sincere regrets to the Clintons." He says the network is hoping the February 26th Clinton-Obama debate will take place as planned.
Shuster tells The Associated Press that he has tried to reach Clinton to apologize.
