On the same day Fox News asked a federal court to toss out a suit brought by former host Andrea Tantaros, the network has lost what is thought to be its first advertiser on Sean Hannity’s show.

Fox News charged that a suit filed April 24 by attorney Judd Burstein on behalf of Tantaros against the network contained allegations that “are not just false, they are outrageously and flagrantly so,” the company said in a motion filed Wednesday in the U.S. District Court for the Southern District of New York.

Tantaros alleges Fox News used electronic surveillance to “emotionally torture” her,  and that it hacked her computer for emails and used Twitter to cyberstalk her, all after she filed a sexual harassment suit in August 2016. That came one month after another former Fox News host, Gretchen Carlson, sued former Fox News CEO Roger Ailes for sexual harassment. She claimed he opted not to renew her contract after she refused to sleep with him.

Since then, Fox has endured the departure and dismissal of many key employees — and growing legal challenges. Those challenges include the April 19 dismissal of star host Bill O’Reilly after reports of harassment allegations against him and a growing advertiser boycott.

One of the supporters of that boycott, liberal activist group Media Matters on Tuesday posted a list of companies that advertise on Hannity’s show, which airs at 10 p.m. ET on Fox News. The Fox News Channel star has done stories about the case of Democratic National Committee employee Seth Rich, who police say they think was murdered in 2016…
