NPR and three Colorado public radio stations are suing the Trump administration over the president's executive order seeking to ban the use of federal money for NPR and PBS.

Trump’s executive order is one of several administration efforts to strip public broadcasting of its federal funding. In January, Federal Communications Commission (FCC) chair Brendan Carr launched an investigation into whether NPR and PBS violated FCC guidelines by airing commercials.

NPR sued the Trump administration Tuesday to block its attempt to revoke federal funding for NPR and PBS—the latest legal battle between President Donald Trump and the media as he’s sought to use his government powers to target organizations he views unfavorably.
