House Democratic leaders on Tuesday criticized Speaker John Boehner, a Republican from Ohio, for increasing the budget for defending the Defense of Marriage Act (DOMA) in court.

In a letter addressed to Boehner, Minority Leader Nancy Pelosi and Minority Whip Steny Hoyer criticized Boehner for increasing the budget to $3 million.

“From the start, the Republican-led campaign to defend DOMA has been a practice in futility and a waste of Americans' hard-earned tax dollars,” the leaders wrote.

After the Department of Justice announced it would no longer defend the law in court, Boehner directed the so-called Bipartisan Legal Advisory Group (BLAG) to step in. BLAG hired former Solicitor General Paul Clement to argue more than a dozen cases challenging the constitutionality of DOMA, which bans federal agencies from recognizing the legal marriages of gay and lesbian couples.

“Let us be clear: these steps do not reflect the will of the House or the consensus of the BLAG. Democrats do not support any decisions to invest taxpayer funds in defense of an indefensible law. We remain united in our opposition to any effort to preserve, protect and defend discrimination in our country,” Pelosi and Hoyer wrote.

BLAG originally committed $500,000 to defend the law.

The Supreme Court in March is scheduled to hear arguments in a case challenging the law's constitutionality.

“We look forward to the day when this measure is declared unconstitutional by the highest court in the land and when all of America's families can know the blessings of equal protection under the law,” Pelosi and Hoyer added.
