Bill Bratton, the former police commissioner of New York City and police chief of Los Angeles, and his wife, TruTV personality Rikki Klieman, have recorded a video urging New Yorkers to support gay marriage.

“We are New Yorkers for marriage equality,” Klieman says as she gazes on at her husband.

“I believe in law and order,” Bratton adds in the 30-second spot. “I've spent my life working to keep communities safe. Marriage equality under the law will make families safer and stronger.”

The couple has previously supported the gay community, including a 2009 appearance in the Los Angeles gay pride parade in West Hollywood.

The ad is part of an ongoing campaign that features prominent celebrities and politicians, including Hollywood couple Ethan and Ryan Hawke, Robert F. Kennedy, Jr., and actress Fran Drescher. The campaign, backed by the Human Rights Campaign (HRC), the nation's largest gay rights advocate, hopes to build momentum on the issue now, ahead of a hoped-for second attempt to legalize the institution later this year.

Two weeks ago, two former New York City mayors – Ed Koch and David Dinkins – joined Michael Bloomberg, the city's current mayor, in recording videos for the campaign.
