Sen. Dianne Feinstein, D-Calif., chair of the Senate Intelligence Committee, tells Transportation Secretary Anthony Foxx to be cautious about the evolution of small, unmanned drone aircraft and the threat to Americans’ privacy, at a Senate Transportation subcommittee hearing on Capitol Hill in Washington, Thursday, March 13, 2014. A dispute between the CIA and Sen. Feinstein flared into public view this week when, in an extraordinary floor speech, she accused the CIA of improperly searching a computer network the spy agency had set up for lawmakers investigating the George W. Bush-era interrogation program for suspected terrorists. (AP Photo/J. Scott Applewhite)
