New York Senator Kirsten Gillibrand has urged House Speaker John Boehner not to defend the Defense of Marriage Act (DOMA) in court, calling such an effort a waste of taxpayer's money.

Last week, President Barack Obama announced he believed parts of the 15-year-old law that bans federal agencies from recognizing the legal gay marriages of gay and lesbian couples are unconstitutional, and asked the Department of Justice to stop defending the law.

“It is in the best interests of taxpayers and the Constitution for you to refrain from appointing special counsel to defend this law,” Gillibrand wrote in a letter to Boehner published Wednesday at “A decision to appoint special counsel would be an unnecessary cost to taxpayers, and would detract from our shared goal of cutting wasteful spending and creating jobs.”

Boehner on Monday said he believed the House would move to defend the law. Republicans have said they'll discuss their options at a press conference scheduled for Friday.

Gillibrand, a supporter of gay marriage, added that she believes the law is unconstitutional.

“At this critical economic juncture in our nation's history, it is imperative that we as legislators do not devote resources to defending an antiquated and unconstitutional law.”
