This bill would prohibit the federal government from granting or renewing security clearances to anyone who has publicly expressed support for foreign terrorist organizations, the Islamic Revolutionary Guard Corps, or their affiliates including Hamas and Hezbollah. The legislation also covers individuals who have ties to or support these organizations. The bill affects federal employees, contractors, and others who seek or hold security clearances across all government agencies with clearance authority. To ensure compliance, the bill requires the Inspector General of the Intelligence Community to audit the clearance processes of federal agencies at least once every two years and certify whether they have effective measures to identify applicants with terrorist sympathies. No specific funding or implementation timeline is specified in the legislation beyond the biennial audit requirement.
