The Trump administration said that it has sent to Congress its proposal to roll back $1.1 billion in funding allocated to public media stations, NPR and PBS, continuing the president’s effort to punish mainstream media.

America’s two big public broadcasters, PBS and NPR, have 45 days to salvage their federal funding — starting now.

The Trump administration formally requested a rescission of funds for the Corporation for Public Broadcasting, seeking to halt federal funding to PBS and NPR.
