Baltimore Ravens linebacker Brendon Ayanbadejo on Monday kicked off a video campaign to legalize gay marriage in more states.

Freedom to Marry, the Human Rights Campaign (HRC) and 80 other groups last year launched the Respect for Marriage Coalition, which is working to build support for the Respect for Marriage Act, the federal bill which seeks to repeal the Defense of Marriage Act (DOMA).

DOMA is the 1996 law which prevents federal agencies from recognizing the legal marriages of gay and lesbian couples.

Ayanbadejo, fresh off the Ravens' Super Bowl XLVII victory, on Monday launched the group's first video.

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

Ayanbadejo also campaigned for passage of a marriage equality law in Maryland.
