President Trump’s campaign on Monday filed a lawsuit against an NBC affiliate in Wisconsin for running an anti-Trump ad the campaign called “false and defamatory,” including the claim that he referred to the coronavirus as “a hoax.”

“Donald J. Trump for President, Inc. today filed a lawsuit against WJFW-NBC of Rhinelander, WI for defamation in the wake of an advertisement carried by the station that contained intentionally false and defamatory statements about President Trump,” the campaign said in a statement.

The suit was filed in Price Count circuit court, and followed a cease-and-desist letter and supporting documents sent last month.

The ad was produced by Priorities USA, a super PAC supporting Joe Biden, and uses Trump’s early quotes dismissing the severity of the coronavirus threat juxtaposed with a graph showing the soaring number of cases in the US.

“One day, it’s like a miracle, it will disappear,” read one of the quotes.

“No, I don’t take responsibility at all,” Trump said in another sound bite.

The ad also features the president’s use of the word “hoax” when discussing the virus.

The ad suggests that he was referring to the virus itself when he uttered it at a campaign rally, while Team Trump argues that he was referring to Democrats’ attacks on his handling of the threat as another hoax, the word he used to dismiss the Russia probe into his campaign and the House vote to impeach him over his call to the president of Ukraine seeking information on Biden.

While the quotes are accurate, the suit contends that the way they were presented creates the false impression that Trump’s statements came during the later stages of the pandemic.

Priorities USA spokesman Josh Schwerin told PolitiFact, a fact-checking organization, that the organization stands by the ad.

But PolitiFact asserted that the ad could mislead people.

“Some viewers might assume that the timing of Trump’s comments matches the growth in U.S. cases that the ad shows. Most of the comments came as cases were just starting to mount,” the fact-checkers said.

The suit is the latest filed by the Trump campaign against a media outlet.

Other media defendants have included CNN, The New York Times and The Washington Post.

Legal experts said the suits would likely go nowhere but could have a chilling effect on media outlets’ coverage of the Trump campaign.

“The concern here is not that one of these suits would win on the merits — it’s the chilling effect that it has on public discussion of political affairs,” Jonathan Peters, the Columbia Journalism Review’s press freedom correspondent, told The Hill.

The Wisconsin suit seeks unspecified damages.
