Mitt Romney says he has accepted an apology from an MSNBC host who joked about a Christmas picture that included the 2012 Republican presidential candidate's adopted, African-American grandson.

Romney told Fox News Sunday that he sees Melissa Harris-Perry's apology as sincere and is ready to move on. He says everyone — himself included — makes mistakes and the Romney family has forgiven MSNBC.

During a segment, Harris-Perry asked her guests to talk about a photo showing 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."

Harris-Perry later said her intention was to celebrate diversity, but the segment took an unexpected and offensive turn.
