A federal judge is probing whether the Department of Defense’s inspector general (IG) destroyed documents related to the case of Thomas Drake, a former National Security Agency official turned whistleblower. Drake endured retaliation from the government and prosecution from the Obama administration for cooperating with other whistleblowers starting a dozen years ago regarding NSA surveillance programs. The Department of Justice tried to convict Drake of violating espionage laws while acting as a whistleblower, but the case fell apart and prosecutors had to settle for getting Drake to plead guilty to a misdemeanor charge.
