House Minority Leader Nancy Pelosi has criticized House Republicans for not disclosing boosting spending to defend the Defense of Marriage Act (DOMA), the 1996 law which bans federal agencies from recognizing the legal marriages of gay and lesbian couples.

According to CQ Roll Call, Republicans raised the cap twice from its original maximum of $500,000. On September 29, 2011 the cap was raised to $1.5 million. A second increase to $2 million was authorized a year later, on September 28.

After the Department of Justice announced it would no longer defend the law in court, House Speaker John Boehner, a Republican from Ohio, directed the so-called Bipartisan Legal Advisory Group (BLAG) to step in. BLAG hired former Solicitor General Paul Clement to argue the cases.

The Supreme Court earlier this month agreed to hear one of those DOMA cases, Windsor v. United States.

In a statement released Thursday, Pelosi blasted House Republicans for “wasting taxpayer dollars to defend the indefensible Defense of Marriage Act.”

“Hiding this contract from voters in the midst of an election season was a cynical move at best, and a betrayal of the public trust at worst,” she said. “Republicans should not be spending $2 million to defend discrimination in our country.”
