This bill, titled the "Defund NPR Act," seeks to prohibit all federal funding for National Public Radio (NPR) and any successor organizations. It amends the Communications Act of 1934 to ensure that no federal funds, directly or indirectly, can be used to support NPR, including through payments from public broadcast stations that receive federal funding. The legislation explicitly prevents public broadcast stations from using federal money to pay dues to NPR or purchase its programming. Furthermore, the bill includes technical and conforming amendments to remove existing statutory references to National Public Radio within the Communications Act, particularly concerning the Corporation for Public Broadcasting's funding mechanisms.
