Former President Bill Clinton was heckled on Saturday night while accepting an award for his support of LGBT rights.

Clinton was presented the first Advocate for Change award at the GLAAD Awards in Los Angeles. While the former president was speaking out against the Defense of Marriage Act (DOMA), which prohibits legally married same sex couples from receiving federal benefits and protections, an audience member angrily reminded him that he signed the bill into law in 1996.

"I want to keep working on this until not only DOMA is no longer the law of the land, but until all people, no matter where they live, can marry the people they love," Clinton said in his acceptance speech. "I believe you will win the DOMA fight, and I think you will win the Constitutional right to marry. If not tomorrow, then the next day or the next day."

GLAAD provided Clinton with the award for opposing efforts to ban same sex marriage in North Carolina and supporting efforts to legalize same sex marriage in New York. The LGBT organization also noted Clinton appointed more than 150 gay and lesbian individuals to all levels of government and helped fight the HIV/AIDS crisis.

During his speech, Clinton explained that he changed his view on same sex marriage thanks to his daughter Chelsea.

"Chelsea and her gay friends have modeled to me how we should all treat each other regardless of our sexual orientation or any other artificial difference that divides us," he explained. Many of them come and join us every Thanksgiving for a meal. I have grown very attached to them. And over the years, I was forced to confront the fact that people who oppose equal rights for gays in the marriage sphere are basically acting out of concern for their own identity, not out of respect for anyone else."
