House Minority Leader Nancy Pelosi on Tuesday criticized legal 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.

At the direction of House Speaker John Boehner, a Republican from Ohio, the so-called Bipartisan Legal Advisory Group (BLAG) stepped in to defend the law in court after the Obama administration declined to do so, saying it believes the law is unconstitutional. BLAG hired former Solicitor General Paul Clement and authorized a $1.5 million budget.

“It is unconscionable for Speaker Boehner and Republican leaders, including Chairman Dan Lungren who authorized the contracts with the outside law firm, to continue to stand on the wrong side of history at taxpayer expense,” said Pelosi in a statement.

“To date, Boehner has intervened in 14 DOMA cases at taxpayer expense and lost five in a row so far,” she added.

House Democrats charge BLAG is about to surpass the $1.5 million cap agreed to last year.

“Despite losing multiple court cases, Speaker Boehner continues to insist on racking up even more taxpayer-funded legal bills, even as Republicans claim to be concerned about the deficit,” said House Minority Whip Rep. Steny Hoyer of Maryland.

The Supreme Court has been asked to review four DOMA challenges. The court has not announced whether it will hear any of those cases.
