It’s been six years since Congress began banning federal employees from watching pornography in the workplace. But even though lawmakers have gradually added the rule to spending bills, implementing it agency by agency, some workers are still pulling up porn — and some departments still aren’t covered.

As the spotlight on sexual exploitation intensifies in Washington and around the nation, it’s clear that the problem of online porn in the federal workplace hasn’t gone away.

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.
