Congresswoman Ileana Ros-Lehtinen has verified her support for marriage equality to the Washington Blade, making her the first GOP member of the House to do so.
Ros-Lehtinen also became the first Republican to sign on as a co-sponsor for a bill repealing the Defense of Marriage Act — called the Respect for Marriage Act — back in September.
