Washington Governor Chris Gregoire has urged President Barack Obama to join her in supporting gay marriage.

During an appearance on Sirius XM's The Michelangelo Signorile Show, Gregoire talked about her recent endorsement of a bill that seeks to make Washington the seventh state to legalize gay marriage.

“I wished I could have come to the point that I am today six years ago, seven years ago, five years ago,” Gregoire said. “But it took me a journey and ... I'm sorry that it took me so long as it did. But it's genuine. It's not about politics. It's very heartfelt. It's about my [Catholic] faith and I have struggled with it.”

She said that response has been overwhelmingly positive.

“I've received thousands of emails and letters and telephone calls. And the one that just hit my heart was a 16-year-old who said, 'I've thought about suicide, and now that you've come out as strong as you have, I feel good about myself. And one day I will not go on bended-knee and ask someone to join me in a domestic partnership, I'll ask them to marry me.' That's the exact thing that moved me to where I am and that's only right for our children in this state and for their parents.”

Obama has said he supports civil unions for gay couples but recently added that he is “evolving” on marriage.

“I think, I hope, the president will evolve in his thinking and his personal journey but I have to respect the journey he's on,” Gregoire said.

“I believe he will get to where I found myself, [New York] Governor [Andrew] Cuomo found himself. But people need to give him the opportunity to get there.”

Supporters of marriage equality say they have the votes to approve the legislation. However, opponents have vowed to challenge the law at the ballot box.
