FCC chair, Republican Brendan Carr, reportedly sent a letter to NPR and PBS announcing the launch of an investigation into potential airing of 'prohibited commercial' ads.

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

Brendan Carr, the President Trump-appointed FCC chairman, warned the CEOs of PBS and NPR that they “could be violating federal law by airing commercials” — and that he has ordered an investigation by the FCC’s Enforcement Bureau into the matter.
