Robert De Niro apologises for well-meant quip
The Raging Bull star was introducing the First Lady, Michelle Obama, at at a Democratic fundraiser in New York, when he made a joke that he now regrets making.
"My remarks, although spoken with satirical jest, were not meant to offend or embarrass anyone - especially the first lady," he said.
During his introduction at Monday's fundraiser, De Niro, 68, alluded to Mr Gingrich's wife, Callista.
"Callista Gingrich, Karen Santorum, Ann Romney. Now do you really think our country is ready for a white first lady? Too soon, right?" he told the audience.
I love it! But, guess what, Republican candidate Newt Gingrich called the remarks "inexcusable".
