Sen. Kirsten Gillibrand (D-N.Y.) tweeted Monday afternoon that she had just spoken with Lady Gaga, who has been lobbying the Senate ahead of Tuesday's vote on a defense authorization bill that includes a repeal provision for "Don't ask, don't tell."

"[I] thanked her for her advocacy,"Gillibrand said. "I asked her to keep pushing for #DADT repeal." 

Gaga had left a message with Gillibrand last week, prompting the senator to reach out on Twitter for another time to talk.

The Grammy Award-winning pop star will attend a rally Monday in Portland, Maine, with veterans discharged because of the policy, which prohibits gays and lesbians in the mili! tary from serving openly.

The outcome of Tuesday's vote is uncertain, because some Senate Republicans have threatened a filibuster. The two key votes will be cast by Maine Republicans Susan Collins, who voted to repeal the policy in committee but wants Republican amendments allowed on the bill, and Olympia Snowe, who hasn't said how she'll vote.
