Amid the mushrooming coronavirus crisis, Rupert and Lachlan Murdoch are girding for a pandemic of public-interest lawsuits over misinformation and conspiracy theories dispensed by certain Fox News Channel and Fox Business Network personalities such as Sean Hannity, Laura Ingraham, and Trish Regan.

According to a top Murdoch executive, the father-and-son media moguls are ready to go to war with potential plaintiffs such as the Washington League for Increased Transparency and Ethics—aka WASHLITE—an activist non-profit that filed suit on Thursday against Rupert Murdoch, Fox News and other defendants.

The 10-page complaint, first reported by The Times of San Diego and filed in the superior court of Washington state’s King County, seeks a judgment that the Murdoch-controlled outlets violated the state’s consumer protection laws by “falsely and deceptively disseminating ‘News’ via cable news contracts that the novel Coronavirus, COVID-19 was a ‘Hoax,’ and that the virus was otherwise not a danger to public health and safety.”
