I do not see a reason why Congress should continue sending taxpayer dollars to NPR and PBS,’ Brendan Carr, the FCC chairman, wrote in a letter.

Federal Communications Commission Chairman Brendan Carr said he is launching investigations into both PBS and NPR, in the hopes of helping Congress defund the public broadcasters. His basis for the investigation stems from what he alleges are potentially unlawful commercials.

The investigation will revolve around NPR and PBS airing sponsorships across their 1,500-plus member stations, FCC Chairman Brendan Carr said.
