Anderson Cooper calls out Obama on gay marriage

Anderson Cooper called out President Obama on his Tuesday show for flip-flopping on gay marriage.

Obama is under increased scrutiny about his "evolving" views on gay rights in the wake of the battle for gay marriage in New York. Obama will be in the state on Thursday to attend a high-priced fundraiser with gay donors.

In his "Keeping Them Honest" segment, Cooper said, "New questions are being raised about what the president actually believes about gay marriage and whether his public opposition to it is real or just political posturing."

He then ran through the by-now familiar tale of President Obama's stance on gay marriage, from his initial written support for it in 1996 to his stated opposition to it when he began running for national office. (Obama advisers recently told The Huffington Post that his current position on the issue is that it should be left up to the states.)

Cooper played footage from the recent Netroots Nation Conference, where White House Communications Director Dan Pfeiffer was grilled about Obama's shifting statements about gay marriage.

"Hard to see how the president's position has changed so much," Cooper said. "The only thing that has changed is his need for a wider audience to vote for him."
