Harold Ford Jr. got a tough reception when he spoke to a gay advocacy group and tried to explain he no longer opposes gay marriage.
The former Tennessee congressman had voted twice for a constitutional amendment defining marriage as a union between a man and a woman.
He spoke Wednesday to the Stonewall Democratic Club of New York and was interrupted numerous times by protesters. They said they don't trust him and shouted that he is "anti-gay.''
Ford said all he can do is explain he was wrong in the past and has changed his mind.
He says he is close to making a decision about whether to run.
