WASHINGTON : Retired US Army general and President-elect Donald Trump's pick as national security adviser, Michael Flynn, was found to have "inappropriately shared" classified information with foreign military personnel, The Washington Post reported Wednesday. The military investigation, launched in 2010, found that Flynn did not act "knowingly" and that "there was no actual or potential damage to national security as a result," resulting in no disciplinary action, the Post reported.

Flynn shared the secrets with British and Australian allies in Afghanistan, the Post reported. "It was a general intelligence briefing that included stuff that shouldn’t have been on those slides," a former senior US intelligence official told the Post. The disclosures revealed "stuff the intelligence community was doing that had a much higher level of classification."

Former US officials have in the past alleged Flynn shared sensitive information with Pakistani military officials about US intelligence capabilities watching an insurgent group.

Flynn was one of many who criticized Hillary Clinton during the campaign for mishandling classified information. During his speech before the Republican National Convention in July, Flynn led the crowd through chants of "lock her up," adding "If I, a guy who knows this business, if I did a tenth, a tenth of what she did, I would be in jail today."
