FBI Director Christopher Wray said that China is the greatest counterintelligence threat facing the U.S. but warned that Russia is a close runner-up as Moscow remains focused on disrupting the upcoming presidential election.

Chairman Lindsey Graham of South Carolina asked Wray about China during his Tuesday testimony before the Senate Judiciary Committee, and Wray replied that “there is no country that poses a more severe counterintelligence threat to this country right now.” Wray added that the second greatest counterintelligence challenge was “probably Russia.”
