Elizabeth Warren, the Democratic candidate attempting to unseat Massachusetts Senator Scott Brown, has said she supports a federal gay marriage law.

The 62-year-old Warren made her comments in an interview with Salon.com at Netroots Nation conference which took place in Providence, Rhode Island.

When asked about President Barack Obama's recent announcement in support of gay marriage, Warren stood up to do a quick celebratory dance, the site reported.

“And I believe DOMA is despicable,” she added. “I'm serious about that.”

The 1996 Defense of Marriage Act (DOMA) bars federal agencies from recognizing the legal marriages of gay and lesbian couples. The law is being challenged in at least 12 separate lawsuits. In recent months, judges in California, Massachusetts and New York have ruled DOMA to be unconstitutional.

While Warren is thrilled with Obama's evolution on marriage equality, she disagrees with the president's stance that the issue should be left up to the states.

When asked whether she supports federal legislation allowing such unions, she gave her unequivocal endorsement: “Yes, I believe in marriage equality. Done. Game. Set. Match.”
