The U.S. Senate has failed to advance a measure that would repeal the military’s ban on openly gay and lesbian servicemembers known as “Don’t Ask, Don’t Tell.” On Thursday, the Senate fell three votes short of advancing a military spending bill with a repeal provision attached. The vote raises the prospect that the ban will not be repealed before Republicans take over the House and weaken the Democrats’ Senate majority next month. In another vote, Republicans also blocked a measure to advance the DREAM Act, a provision that would grant undocumented young people a chance at citizenship. Republicans also blocked a measure to provide up to $7.4 billion to workers sickened during the cleanup at the World Trade Center following the 9/11 attacks. The measure passed the House earlier this year.
