Ohio Senator Rob Portman will become the first Senate Republican to co-sponsor legislation repealing the Defense of Marriage Act (DOMA).  So says to a gay GOP group.

Gregory Angelo, the newly installed executive director of Log Cabin Republicans, told gay weekly the Washington Blade that he expects Portman will back the proposed legislation.

“Congresswoman Ileana Ros-Lehtinen and Congressman Richard Hanna were Republican co-sponsors in the 112th Congress, and we have every expectation they will continue as co-sponsors when the bill is reintroduced,” Angelo said. “Given his recent evolution on marriage equality, we expect Republican Senator Portman to be a co-sponsor in the Senate.”

In March, Portman announced in an op-ed that he had reversed course on the issue of marriage equality and credited his son's recent coming out for changing his heart.

However, in his original remarks on the subject, Portman said that “change should come about through the democratic process in the states,” and he also warned against “judicial intervention from Washington.”

“An expansive court ruling would run the risk of deepening divisions rather than resolving them,” he wrote.

Reintroduction of the legislation, known as the Respect for Marriage Act, is being delayed until after the Supreme Court hands down a much-anticipated ruling on DOMA in June.
