PORTLAND — Known for her bold statements and even bolder attire, pop diva Lady Gaga arrives in Portland Monday afternoon to stomp for a political platform she launched last week during the MTV Video Music Awards.

The Washington Post reported Sunday night that the celebrated musician will speak out at a political rally aimed at pressuring Maine U.S. Sens. Susan Collins and Olympia Snowe to vote Tuesday in favor of the annual defense appropriations bill that includes language repealing the law prohibiting gays and lesbians from serving in uniform.

The law is enforced by the infamous “don’t ask, don’t tell” policy” established in 1993 by an executive order of then-President Bill Clinton.

According to The Washington Post, Senate Majority Leader Harry Reid plans to hold a cloture vote on the annual defense appropriations bill Tuesday afternoon. Collins and Snowe have yet to announce how they plan to vote.

The D.C.-based newspaper reports that a group led by Sen. John McCain, R-Ariz., are threatening to vote against cloture to protest Reid’s plans to add an immigration-related amendment to the defense bill, arguing that unrelated amendments should not be added to a bill setting military policy.

Gaga will join representatives of the Servicemember’s Legal Defense Network, a legal group assisting troops impacted by the law, during a rally at 4 p.m. in Deering Oaks Park.

The Portland Press Herald reported Sunday night that Aubrey Sarvis, executive director of the Service Members Legal Defense Network, said Lady Gaga is a passionate supporter of repealing the policy. She went on to say that the musician views Maine’s two Republican senators as holding critical votes to breaking a threatened Republican filibuster.
