The Public Broadcasting Service (PBS) is suing the Trump administration over its attempts to defund the television network, writes The Hollywood Reporter. The suit mirrors a similar one filed on Monday by National Public Radio (NPR) in response to the President’s recent Executive Order 14290, which endeavors to abolish all federal funding for both organizations.

Trump first declared his intent to defund the two networks on May 1st, alleging an anti-conservative bias on the part of the broadcasters, which are funded by a combination of governmental and nongovernmental sources. The official White House website claims that “NPR and PBS have fueled partisanship and left-wing propaganda with taxpayer dollars, which is highly inappropriate and an improper use of taxpayers’ money.”

The networks argue, though, that such efforts constitute a blatant violation of the First Amendment. “The EO makes no attempt to hide the fact that it is cutting off the flow of funds to PBS because of the content of PBS programming and out of a desire to alter the content of speech,” reads the lawsuit, which was filed in a U.S. District Court in the nation’s capital according to The Hollywood Reporter. “That is blatant viewpoint discrimination and an infringement of PBS and PBS Member Stations’ private editorial discretion.”

Per the White House, both PBS and NPR receive their federal funding through the Corporation for Public Broadcasting, a publicly-funded nonprofit created in 1967 with the intent of supporting public broadcast. While the lawsuit is still in an early stage, the ultimate outcome of the lawsuit might depend on whether Trump is allowed to instruct the center where they are permitted to allocate their funds.

A spokesperson for PBS cited “careful deliberation” as a reason behind the lawsuit to The Hollywood Reporter, stating that “PBS reached the conclusion that it was necessary to take legal action to safeguard public television’s editorial independence, and to protect the autonomy of PBS member stations.”

“If allowed to stand, the EO would override Congress’s decision to remove the administration of federal funding for public television from the government’s editorial purview,” concludes the filing, according to The Hollywood Reporter. “And it would have profound impacts on the ability of PBS and PBS Member Stations to provide a rich tapestry of programming to all Americans.”
