Former U.S. Secretary of State Hillary Rodham Clinton looks into the crowd after a person threw an object at her while speaking during The Institute of Scrap Recycling Industries' annual conference at the Mandalay Bay hotel-casino on Thursday, April 10, 2014, in Las Vegas. Clinton, a possible presidential contender in 2016, ducked but did not appear to be hit by the object, and then joked about the incident. Security ushered out a woman who said she threw a shoe but didn't identify herself to reporters or explain the action.
