A broad coalition of progressive groups in Rhode Island will begin work advocating for gay marriage on Monday.

Rhode Islanders United for Marriage's first official press conference will feature several community leaders.

Bills seeking to make Rhode Island the 10th state to legalize marriage equality were introduced in both houses earlier this month.

The Rhode Island House on Tuesday is expected to hold a hearing on the proposed legislation, setting up a potential vote in the chamber before month's end. Previous hearings on the issue went long into the night and attracted hundreds of people.

The new organization includes Freedom to Marry, Gay and Lesbian Advocates and Defenders (GLAD), Gill Action, the Gay and Lesbian Alliance Against Defamation (GLAAD), the Human Rights Campaign (HRC), Marriage Equality Rhode Island, Marriage Equality USA, National Association of Social Workers, National Education Association Rhode Island, Ocean State Action, Planned Parenthood of Rhode Island, Rhode Island ACLU, Rhode Island AFL-CIO, Rhode Island Democratic Party LGBTQ Caucus, Rhode Island Federation of Teachers and Health Professionals, Rhode Island National Organization for Women, Rhode Island Pride, Rhode Island Progressive Democrats, Rhode Island State Council, SAGE/RI, Service Employees International Union, United Auto Workers (Region 9A), United Food and Commercial Workers (Local 328) and Youth Pride Incorporated.
