Director of National Intelligence James Clapper has reportedly admitted making incorrect statements about sweeping National Security Agency spying. At a congressional hearing in March, Clapper was asked whether the NSA collected data on millions of Americans. He replied, “No.” When pressed, he added, “Not wittingly.” But according to The Washington Post, Clapper sent a letter to the Senate Intelligence Committee last month saying he misunderstood the question. “I have thought long and hard to re-create what went through my mind at the time,” Clapper wrote. “My response was clearly erroneous — for which I apologize.”
