Maryland Governor Martin O'Malley on Friday said he would strongly back a new push for gay marriage in his state, the AP reported.

O'Malley made his remarks at the National Governors Association meeting in Salt Lake City.

On Tuesday – less than four months after a marriage bill was suddenly shelved in the Maryland House after passage in the Senate – proponents of gay marriage unveiled a broader campaign to win marriage equality in the state.

The push in Maryland will be spearheaded by the nascent group Marylanders for Marriage Equality, which will include Equality Maryland, Freedom to Marry, Progressive Maryland, labor unions Service Employees International Union and Communications Workers of America, and the American Civil Liberties Union.

Also involved is the nationwide gay rights group Human Rights Campaign (HRC), the group behind the yearlong – seemingly unending – campaign of celebrity video endorsements.

Proponents had called on the Democratic governor, who supported this year's bill, to take on a more visible role in advocating for the measure.

“I think that would really help build our chances next session if the governor was one of the chief people advocating for this bill vocally,” Darrell Carrington told the “That would have a huge effect on the outcome.”

New York Governor Andrew Cuomo played a critical role in the passage of a gay marriage bill that takes effect in the Empire State on July 24.
