By Michael Zennie and Reuters Reporter PUBLISHED: 16:15 EST, 17 April 2013 | UPDATED: 19:09 EST, 17 April 2013 The U.S. Senate has voted down a bipartisan plan to expand background checks for gun buyers, rejecting the last viable gun control proposal put forward by President Barack Obama after the Newtown school massacre. The measure failed by a vote of  54-46, six Senators short of the 60-vote hurdle needed for passage. A furious President Barack Obama blasted the Senate shortly after the vote. He said it was shameful that a bill 'supported by 90 percent of Americans' had failed.
