security clearance revocation

I thought we would take a step back in time and take a look at a security clearance denial case that occurred in 1954. Most people have heard of Robert Oppenheimer, world renowned physicist and his contribution to science. What may be less known is he was accused of disloyalty

After sending two emails containing classified information on an unclassified network to unauthorized recipients, a U.S. Air Force civilian employee was fired and his clearance was revoked.
