Maryland Gov. Martin O'Malley (D) will move forward Friday with plans to announce his sponsorship of a same-sex marriage bill during next year’s legislative session, aides said.

O'Malley has been trending in this direction for more than a week, but the timing of the event remained in flux in recent days. In an interview last week, the governor said he was “certainly leaning” toward making a same-sex marriage bill part of his legislative package next year.

An announcement has been planned for 2 p.m. Friday at the State House in Annapolis.

O'Malley had expressed support for a same-sex marriage bill that fell short during this year’s legislative session, but his lobbying efforts were limited largely to private conversations with lawmakers.

In the wake of New York’s recent embrace of same-sex marriage, gay legislators and other advocates in Maryland have been pressing O'Malley to play a far more visible role next year.
