This legislation, known as the Nonprofit Security Grant Program Transparency Act, aims to significantly improve the oversight and accountability of the Nonprofit Security Grant Program (NSGP) by amending the Homeland Security Act of 2002 to mandate comprehensive reporting requirements for the program's administration. Specifically, the bill requires the Administrator to submit a pre-grant report to congressional committees at least seven days before any grants are awarded in a fiscal year. This report must include detailed information such as the number of applications received, the number of grants to be made disaggregated by state and high-risk urban area, and the aggregate amount of these grants. Crucially, it also requires the disclosure of each recipient organization's name, address, location within a high-risk urban area if applicable, and the specific grant amount they are set to receive. Furthermore, an annual report is mandated within 90 days after the conclusion of each fiscal year, providing an overview of the program's activities. This includes the total number of applications, grants made, and aggregate amounts per state, along with details on how grant funds were expended by recipients and information regarding the operations and staffing resources of the program office, ensuring ongoing transparency and evaluation of the NSGP's effectiveness.
