This bill establishes a comprehensive prohibition on the allocation of funds to the National Endowment for Democracy. Specifically, it mandates that the head of any federal agency is forbidden from providing financial support to the organization. The legislation defines "agency" by referencing existing federal law, ensuring that the prohibition applies broadly across the U.S. government. The primary impact of this bill would be to eliminate all direct federal funding for the National Endowment for Democracy's operations and programs, thereby ceasing government financial support for its activities.
