Republican Sen. Lindsey Graham has revealed what he says is the death toll in the U.S. drone war overseas. At a speech in South Carolina Wednesday night, Graham said: “We’ve killed 4,700. Sometimes you hit innocent people, and I hate that, but we’re at war, and we’ve taken out some very senior members of al-Qaeda.” Graham’s comments mark the first time a U.S. official has offered a figure for those killed in nearly a decade of U.S. drone strikes abroad. The 4,700 figure matches the high end of an estimate by the Bureau of Investigative Journalism, which has extensively covered the strikes and faced a concerted U.S. government effort to discredit its work.
