MSNBC host Melissa Harris-Perry apologized to former Republican presidential candidate Mitt Romney and his family for joking about a Christmas picture that showed his adopted African-American grandson.
Harris-Perry said her intention was to celebrate diversity, but the segment took an offensive turn when her panelists started joking about the baby not fitting in.
One guest on her Sunday show, actress Pia Glenn, sang "one of these things just isn't the same." Comedian Dean Obeidallah said it "sums up the diversity of the Republican party."
MSNBC was forced to issue other apologies in 2013.
Host Martin Bashir apologized and resigned late last year after he made graphic remarks about former Alaska Gov. Sarah Palin.
The network also suspended actor Alec Baldwin from his weekly show for two episodes because he used an anti-gay slur in a confrontation with a photographer on a New York City street. Baldwin apologized and he and the network ended his show after five episodes.
