The Transportation Security Administration has issued a final rule on airport body scanners, nearly five years after the D.C. Circuit Court of Appeals ordered the agency to "promptly" solicit public comments on the controversial scanners. In 2011, EPIC successfully challenged the TSA's unlawful deployment of airport body scanners. Despite public comments that overwhelmingly favor less invasive security screenings, the agency will continue to use invasive body scanners at airports. The agency also states that it may mandate airport body scanners. EPIC and 25 organizations have urged Congress to hold a hearing on TSA's decision to end the opt-out for airport body scanners. The agency previously informed the D.C. Circuit that the body scanner program was optional. The Court concluded because "any passenger may opt-out of AIT screening in favor of a patdown" there was no violation of the Fourth Amendment.
