WATCH: Political Opponent Slams Christie on Same-Sex Marriage Stance

A political opponent slammed Chris Christie for his opposition to marriage equality during a Tuesday debate.

New Jersey state senator Barbara Buono, who is challenging Christie in the state's gubernatorial race, declared to the governor that her daughter is "not a political agenda."

The remarks were in response to a statement Christie had made earlier in the day to a patron of a New Jersey diner, in which he claimed same-sex marriage was not a human rights issue. He compared it to an issue like gun control and expressed his belief that its legality should be decided by voters.

"I trust the people of New Jersey to make this judgment," Christie said during the debate at William Paterson University. "I don't trust 121 politicians with political agendas."

"My daughter, who is openly gay, is not a political agenda," Buono fired back.

Buono's youngest daughter, Tessa Bitterman, is a 22-year-old law student who identified as a "gay American ... deeply shocked by Chris Christie" in a statement released earlier this year.

"As a gay American I have a stake in what our governor says about marriage equality," Bitterman wrote. "And I have been deeply shocked by Chris Christie. As governor, he has been a giant roadblock to New Jersey achieving equality for all. By failing to support marriage equality, Christie is blatantly delegitimizing an entire group of people."
