NEW YORK (AP) - An MSNBC host is apologizing to Mitt Romney's family after she and guests on her show joked about a Christmas picture that showed the 2012 Republican presidential candidate's adopted, African-American grandson.

Melissa Harris-Perry said Tuesday her intention was to celebrate diversity, but the segment took an unexpected and offensive turn. The photo shows infant Kieran Romney with his grandparents and their 21 other grandchildren, all of them white.

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."

Harris-Perry said she'd like to see Kieran marry Kanye West's daughter so West and Romney would be in-laws.
