The Defense Authorization Act, which included a provision to repeal Don't Ask, Don't Tell, has failed to gain cloture in the Senate, 57-40. After signaling that she'd oppose the bill, Senator Susan Collins was the only Republican to vote in favor of cloture.
Republican senators Lisa Murkowski and Scott Brown previously said that they would vote for the bill if the GOP was allowed to debate and offer amendments. Democratic Senate majority leader Harry Reid didn't give the Republicans the chance. As Ben Smith writes, "Expect a lot of anger at Harry Reid for the management of this legislation, in which there seem to have been 61 votes available at some point."
It's also important to note the letter all Republican senators sent Reid last week, which stated: "we write to inform you that we will not agree to invoke cloture on the motion to proceed to any legislative item until the Senate has acted to fund the government and we have prevented the tax increase that is currently awaiting all American taxpayers." Both of these provisions have not been met.
