The Portland Timbers and the Portland Thorns FC have backed a proposed initiative that seeks to repeal the state's 2004 gay marriage ban and legalize such unions.

Peregrine Sports, which owns the soccer clubs, made its endorsement in a 30-second video released through the Oregon United for Marriage campaign.

“On behalf of the Portland Timbers and the Portland Thorns and our owner Merritt Paulson, we are proud today to endorse Oregon United for Marriage's efforts to extend the right to marriage to all loving and committed couples,” COO Mike Golub said in the video. “We believe it's time for Oregon to recognize this fundamental right and we hope you will join us, the Timbers and Thorns, and affirm this right to marry at the ballot next November.” (The video is embedded on this page.

Supporters began collecting signatures in August and have until next summer to collect the 116,284 valid signatures needed to qualify for the November 2014 ballot.

If the measure is approved next year, Oregon would make history as the first state to repeal a constitutional amendment limiting marriage to heterosexual couples.
