Another Senate Democrat has come out in support of same-sex marriage, which leaves six Senate Democratic holdouts who have yet to embrace marriage equality. Today, Sen. Bill Nelson, D-Fla., flipped and announced that he now supported same-sex marriage.

The senator made the announcement during an interview today with the Tampa Bay Times, saying, "It is generally accepted in American law and U.S. society today … that all men are created equal, that they are endowed by their creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. I believe that. The civil rights and responsibilities for one must pertain to all," he told the Tampa Bay Times.

Nelson later confirmed his switch to ABC News.
