Roll Call was able to identify 69 cases of federal employees or others using federal networks to access pornography since Congress began rolling out the ban in November 2011. At least 27 occurred at departments where the rule was already in place.

The Department of Veterans Affairs was one of the first to be covered. But an employee at a VA Medical Center in Kerrville, Texas, regularly downloaded child pornography on his work computer during his midnight shift, according to an inspector general report from the spring of 2014. He was arrested and sentenced to 46 months in prison.

At the National Oceanic and Atmospheric Administration, an employee downloaded “14 adult pornographic video files, 92 adult pornographic images, and 3 unauthorized computer programs,” auditors reported more than a year after the ban took effect for the Commerce Department.
