Baltimore Ravens linebacker Brendon Ayanbadejo urges Marylanders to support gay marriage in a new PSA.

Ayanbadejo is the first professional athlete to endorse the Marylanders for Marriage Equality campaign.

“I believe we should be doing everything that we can to make Maryland families stronger. Which is why I support marriage for gay and lesbian couples who want to make a lifetime commitment to each other,” Ayanbadejo says in his 30-second ad. “People from all walks of life, including gay and lesbian couples, want their children to be in stable homes and protected under the law.”

Maryland Governor Martin O'Malley kicked off the video campaign earlier this month.

Just weeks after New York became the sixth state to legalize gay marriage, O'Malley announced he would follow in New York Governor Andrew Cuomo's footsteps and shepherd a marriage bill through the Maryland Legislature during the upcoming legislative session. Last year, an effort to legalize the institution failed in the House of Delegates after passage in the Senate.

In his ad, O'Malley argues that marriage equality and religious freedoms can coexist. Pressure from religious groups has been credited for ending last year's effort.
