PORTLAND, Maine – Pop star Lady Gaga visited the state Monday on the eve of a key Senate vote to urge its two U.S. senators to help repeal the military's "don't ask, don't tell" policy on gays.

More than 2,000 people attended a rally at Deering Oaks Park, where the Grammy Award-winning singer stood alongside Air Force, Army and Marine veterans who were discharged because of the policy, which prohibits service members from revealing if they're gay and recruiters from asking about people's sexual orientations.

Lady Gaga railed against what she called the injustice of having goodhearted gay soldiers booted from military service while straight soldiers who harbor hatred toward gays are allowed to fight for their country. She suggested a new policy should target straight soldiers who are "uncomfortable" with gay soldiers in their midst.

"Our new law is called 'If you don't like it, go home!'" she said.
