Kathryn Lehman, a lesbian Republican who worked on the Defense of Marriage Act (DOMA), is now lobbying for its repeal.

DOMA is the 1996 law that bans federal agencies from recognizing the marriages of gay and lesbian couples.

The Huffington Post reported that in her capacity as chief counsel for the House Judiciary Committee's Subcommittee on the Constitution, Lehman helped write the law.

Lehman, who at the time was involved in a relationship with a man she eventually married, said the perception America had of gay people was completely different in 1996.

“There was nobody married, it wasn't allowed anywhere,” he said. “The view of gay people … it wasn't Ellen [DeGeneres]. It wasn't Neil Patrick Harris. It was kinky sex and women riding around on motorcycles without skirts on. That was sort of the view that the community projected as well.”

After her marriage failed in 2001, Lehman came to terms with her sexual orientation and began dating women.

But it wasn't until 2009 while reading a legal brief by Ted Olson, the Republican attorney challenging California's gay marriage ban, Proposition 8, that Lehman began to recognize the harm DOMA caused.

“Traditionally, women didn't work outside the home. Traditionally, in the South, black people sat in the back of the bus,” she said. “It's all part of things traditionally that have changed for the better.”

Last year, she began lobbying House Republicans on behalf of Freedom to Marry to support repeal of DOMA.

“I sort of feel like I'm uniquely suited to do this,” Lehman, 52, said.
