Minnesota Senator Amy Klobuchar favors repeal of the Defense of Marriage Act (DOMA), the Minnesota Independent reported.

Klobuchar is one of only two Democrats on the Senate Judiciary Committee who have yet to co-sponsor the legislation. The other undeclared Democrat is Wisconsin Senator Herb Kohl. No Republican members of the committee have publicly declared their support for repeal.

DOMA bans federal recognition of the legal marriages of gay and lesbian couples and allows states to ignore the legal gay marriages of other states.

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.

“I have spoken directly with Amy Klobuchar's State Director,” Minnesota State Senator Scott Dibble wrote on Facebook. “Senator Klobuchar will be voting for the repeal of DOMA in the Senate Judiciary Committee.”

Klobuchar's support is critical for the measure to reach the Senate floor. Kohl appears to hold the deciding vote.

The effort in the Senate to bury the law was introduced at a press conference last week 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.
