The lawsuit came three days after a similar case by NPR, which also saw its funds cut.

PBS has filed a lawsuit against United States President Donald Trump and other administration officials to block his order stripping federal funding from the 330-station public television system, three days after NPR did the same for its radio network.

In its lawsuit filed on Friday, PBS relied on similar arguments, saying Trump was overstepping his authority and engaging in “viewpoint discrimination” because of his claim that PBS’s news coverage is biassed against conservatives.

“PBS disputes those charged assertions in the strongest possible terms,” lawyer Z W Julius Chen wrote in the suit, filed in US District Court in Washington, DC. “But regardless of any policy disagreements over the role of public television, our Constitution and laws forbid the President from serving as the arbiter of the content of PBS’s programming, including by attempting to defund PBS.”

It was the latest of many legal actions taken against the administration for its moves, including several by media organisations impacted by Trump’s orders.

PBS was joined as a plaintiff by one of its stations, Lakeland PBS, which serves rural areas in northern and central Minnesota. Trump’s order is an “existential threat” to the station, the lawsuit said.

A PBS spokesman said that “after careful deliberation, 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”.

‘Lawful authority’

Through an executive order earlier this month, Trump told the Corporation for Public Broadcasting and federal agencies to stop funding the two systems. Through the corporation alone, PBS is receiving $325m this year, most of which goes directly to individual stations.

The White House deputy press secretary, Harrison Fields, said the Corporation for Public Broadcasting is creating media to support a particular political party on the taxpayers’ dime.

“Therefore, the President is exercising his lawful authority to limit funding to NPR and PBS,” Fields said. “The President was elected with a mandate to ensure efficient use of taxpayer dollars, and he will continue to use his lawful authority to achieve that objective.”

PBS, which makes much of the programming used by the stations, said it gets 22 percent of its revenue directly from the feds. Sixty-one percent of PBS’s budget is funded through individual station dues, and the stations raise the bulk of that money through the government.

Interrupting ‘a rich tapestry of programming’

Trump’s order “would have profound impacts on the ability of PBS and PBS member stations to provide a rich tapestry of programming to all Americans”, Chen wrote.

PBS said the US Department of Education has cancelled a $78m grant to the system for educational programming, used to make children’s shows like Sesame Street, Clifford the Big Red Dog and Reading Rainbow.

For Minnesota residents, the order threatens the Lakeland Learns education programme and Lakeland News, described in the lawsuit as the only television programme in the region providing local news, weather and sports.

Besides Trump, the lawsuit names other administration officials as defendants, including Education Secretary Linda McMahon, Treasury Secretary Scott Bessent and Homeland Security Secretary Kristi Noem. PBS says its technology is used as a backup for the nationwide wireless emergency alert system.

The administration has fought with several media organisations. Government-run news services like Voice of America and Radio Free Europe/Radio Liberty are struggling for their lives. The Associated Press has battled with the White House over press access, and the Federal Communications Commission is investigating television news divisions.
