The Supreme Court has decided not to hear a challenge to the Pentagon’s “don’t ask, don’t tell” policy that bars gays and lesbians from serving openly in the military. The court refused to hear an appeal from a former Army captain who was dismissed under the policy. The Obama administration had urged the court to throw the case out. In a brief, the Obama administration had said the “don’t ask, don’t tell” policy is “rationally related to the government’s legitimate interest in military discipline and cohesion.” While running for president, Senator Obama campaigned to end the “don’t ask, don’t tell” policy, but he has made no specific move to do so since taking office in January.
