WATCH: Minn. Republican Tears Up, Regrets DOMA Vote

Rep. Lynne Osterman

A former Minnesotan lawmaker who voted to ban same-sex marriage teared up when she testified before the state house on Monday, saying that she wished she had never voted for it.

"It was incredibly counter-intuitive for me to tell citizens how the government wanted them to live their lives," former Rep. Lynne Osterman said. "I didn't come to St. Paul to single out same-sex families, but in my only term as a member...I cast a politically expedient vote in favor of DOMA, and I have regretted that ever since."

Osterman only served one term in office, but she said that voting in favor of the law was politically expedient, and not fair.

"A 'no' vote is not fair, it's not respectful, and it's not equal," she said to current lawmakers. "I blew my vote, and I'm imploring you, please get this right."
