Newt Gingrich said Tuesday that President Barack Obama should apologize for a joke made by actor Robert De Niro.

"Callista Gingrich. Karen Santorum. Ann Romney. Now do you really think our country is ready for a white first lady?" De Niro said at an Obama fundraiser in New York City on Monday night.

“Too soon, right?," he added.

Gingrich said the joke was "inexcusable" and divided the country.

“If people on the left want to talk about radio talk show hosts, then everybody in the country ought to hold the president accountable when somebody at his event says something as utterly, totally unacceptable as Robert De Niro said last night, and I call on the president to apologize for him.”
