If you though U.S. Sen. Kirsten Gillibrand was demobilizing her supporters following her landslide victory over Republican Wendy Long, think again.

Gillibrand, who pushed for the repeal of the military’s don’t ask, don’t tell policy, released an email to supporters on the news that the Supreme Court would take up two challenges to anti-same-sex marriage laws, including a New York case over the federal Defense of Marriage Act, or DOMA.

In the email, Gillbirand urges recipients to sign a petition backing the repeal of DOMA.

She calls the decision by the high court to take up the cases “truly historic.”

From her email:

“Over the last 6 months, both the first and second federal appeals courts have declared DOMA unconstitutional, and now, for the first time since DOMA was signed into law in 1996, the nation’s highest court will make its voice heard. Momentum across the country is clearly growing towards recognizing the marriages of all loving and committed couples and finally putting the discriminatory DOMA policy into the dustbin of history. But even as DOMA heads to the Supreme Court, it is still incumbent upon Congress to pass the Respect For Marriage Act, which would not only repeal DOMA, but would also put in place much-needed protections for legally married same-sex couples.”
