Wisconsin Senator Herb Kohl favors repeal of the Defense of Marriage Act (DOMA).

Kohl is the remaining Democrat on the Senate Judiciary Committee who has yet to co-sponsor the legislation that aims to repeal the law that bans the federal government from recognizing the marriages of gay and lesbian couples.

The California-based gay rights group Courage Campaign had mounted a campaign urging Kohl to co-sponsor the bill.

“We just heard from Sen. Kohl's office: he will become the 10th and final vote we need on the Senate Judiciary Committee to pass S. 598, the Respect for Marriage Act, out of committee,” the group wrote in a blog post.

Democrats renewed an effort to repeal the law after President Barack Obama announced he would no longer defend the law in court. Obama said he believed parts of the law were unconstitutional.

The effort in the Senate to bury the law was introduced at a press conference last month by California Senator Dianne Feinstein. The Democrat announced her bill flanked by Democratic Senators Kirsten Gillibrand of New York, Chris Coons of Delaware and Richard Blumenthal of Connecticut. Feinstein, Coons and Blumenthal also serve on the Judiciary Committee.
