One of the plaintiffs who sued the state of Oregon to marry his partner is throwing his support behind Wehby.
Ben West is featured prominently in an ad just hitting the airwaves.
"Whether it's standing up for equality for the unemployed or for the next generation, we need leaders who have the courage to do what's right. That's why I support Monica Wehby for Senate. I know she'll fight for every Oregon family, including mine."
In the past, Wehby has said she doesn't have a problem with gay marriage, but doesn't believe it's a government decision.
Her opponent, Senator Jeff Merkley released a statement after the ads starting airing, saying as a long time advocate for equality and opportunity for our LGBT community, he welcomes Wehby's change of heart in support of marriage equality.
