ABC News’ Devin Dwyer reports: The hottest pop music star in America continued her push for a repeal of the military’s Don’t Ask Don’t Tell policy with a new web video addressed to prominent Senate Republicans, who have threatened to filibuster the measure when it comes up for a vote next week. “We are not asking you to agree with or approve the moral implications of homosexuality,” said a somber Lady Gaga, dressed in a black suit against a backdrop of an American flag. “We are asking you to do your job: to protect the Constitution.” Gaga called the policy, which bars gays from serving openly in the military and resulted in the discharge of thousands of veterans, “unconstitutional” and “unfairly enforced.” “Senators, when you’re sending our men and women to war, when you’re sending our wives, husbands, sons and daughters into combat, will you honor their service? Will you support repealing this law on Tuesday and pledge to them that no American’s life is more valuable than another?” she said. Gaga then takes her cell phone (at four and a half minutes into the seven minute video) and calls both New York Democratic Sens. Chuck Schumer and Kirsten Gillibrand but is not able to get through to either. Schumer’s line rang for over a minute and disconnected. Gillibrand’s voicemail box was full. “I will not stop calling until I reach them to tell them to vote with Sen. Harry Reid to end John McCain’s ‘shameless filibuster,’” she said. Gillibrand has been one of the most outspoken advocates for repealing Don’t Ask Don’t Tell. She later tweeted to Lady Gaga: @ladygaga Thx for calling. I couldn’t agree more and am helping lead the fight to repeal DADT. Do you have a moment to talk later today?
