No let-up in spying amid tit-for-tat Russian sanctions - U.S official

WASHINGTON (Reuters) - Russia still runs a versatile spying campaign against the United States despite sanctions and daily publicity about Moscow's interference in the 2016 U.S. presidential election, the top U.S. counter-intelligence official said in an interview.

William Evanina, the National Counterintelligence Executive, described a wide array of challenges his agency faces: hacking of government and industry secrets; industrial espionage; government employees and contractors who share secrets with the news media and groups such as WikiLeaks and foreign acquisition of strategic U.S. industries.
