(NBC News) A civilian NSA employee recently resigned after being stripped of his security clearance for allowing former agency contractor Edward Snowden to use his personal log-in credentials to access classified information, according to an agency memo obtained by NBC News.
In addition, an active duty member of the U.S. military and a contractor have been barred from accessing National Security Agency facilities after they were “implicated” in actions that may have aided Snowden, the memo states. Their status is now being reviewed by their employers, the memo says.
The Feb. 10 memo, sent to congressional intelligence and judiciary committees this week, provides the first official account of a sweeping NSA internal inquiry aimed at identifying intelligence officials and contractors who may been responsible for one of the biggest security breaches in U.S. history. The memo is unclassified but labeled “for official use only.”
