Sen. Kirsten Gillibrand (D-N.Y.) on Monday joined the chorus of lawmakers hoping the Senate stays in session until it's approved a repeal of the military's "Don't ask, don't tell" policy.

Gillibrand, a top foe of the military's prohibition of openly gay or lesbian members, said she agreed with Sen. Joe Lieberman (I-Conn.) that the Senate shouldn't adjourn until it's passed a defense bill containing the DADT repeal.

She tweeted on Monday:

I agree with Sen. @JoeLieberman — Senate shld stay in session until we repeal #DADT

It's not clear these senators might succeed in keeping the Senate in session. Even if Senate Majority Leader Harry Reid (D-Nev.) decides to keep the chamber in session past Dec. 17, when he's said they would wrap up their business for the year, Republicans have vowed to not let the "Don't ask, don't tell" repeal proceed until a tax cut debate has finished.
