California Senator Dianne Feinstein will join New York Representative Jerrold Nadler in a renewed push to end the Defense of Marriage Act (DOMA), the Clinton-era law that bans federal agencies from recognizing the legal marriages of gay and lesbian couples and allows states to ignore such marriages.

Nadler introduced the Respect for Marriage Act in September, 2009. The bill quickly rounded up 100 co-sponsors in its first 30 days and then fizzled. The effort failed to attract a Senate sponsor.

Attorney General Eric Holder's Wednesday announcement that he and President Obama believe parts of the law to be unconstitutional have renewed the effort, Nadler told The Huffington Post.

“The president's move is another step in the increasing realization that there is no conceivable justification for DOMA, that it is motivated, was motivated, purely by irrational considerations and fear and that there is no rational basis that will stand up to a constitutional challenge,” Nadler said.

“Hopefully, that will make it somewhat easier to pass legislation in Congress,” the Democrat added.

Feinstein told the website that she's prepared to back the effort in the Senate.

“As a Member of the Judiciary Committee, it is my intention to introduce legislation that will once and for all repeal the Defense of Marriage Act,” Feinstein said. “My own belief is that when two people love each other and enter the contract of marriage, the Federal government should honor that. I opposed the Defense of Marriage act in 1996. It was the wrong law then; it is the wrong law now; and it should be repealed.”
