This bill requires the Government Accountability Office (GAO), an independent congressional watchdog agency, to conduct annual assessments of whether the Transportation Security Administration's passenger security screening practices comply with its own non-discrimination policies. The first assessment must be completed within 90 days of the bill becoming law, with subsequent assessments due every year thereafter. These assessments will be submitted to the House Committee on Homeland Security and the Senate Committee on Commerce, Science, and Transportation. The bill affects the TSA and all airline passengers by establishing ongoing oversight to identify and address any discriminatory practices in airport security screening. No specific funding amount is provided in the legislation, as the costs would likely be covered within the GAO's existing budget.
