A federal judge on Friday dismissed a lawsuit against Fox News filed by a former on-air host, Andrea Tantaros, who had alleged that the network retaliated against her after she complained about being sexually harassed.
Ms. Tantaros had claimed that Fox News’s founding chairman, Roger Ailes, arranged for her to be illegally surveilled, and that the network’s executives had schemed to create fake social media accounts, known as “sock puppets,” that defamed her online.
On Friday, however, Judge George B. Daniels of the United States District Court for the Southern District of New York wrote that Ms. Tantaros’s allegations were “based primarily on speculation and conjecture.” In dismissing the suit, the judge noted that Ms. Tantaros “fails to adequately make out the basic elements of her claims.”
It was the second legal action against Fox News to conclude this week, as the network looks to move on from a series of scandals that started nearly two years ago. On Tuesday, Fox News reached a $10 million settlement to end a group of racial and gender discrimination lawsuits.
The dismissal of Ms. Tantaros’s lawsuit was a clear victory for the network, which had denied her claims. A spokeswoman for Fox News said on Friday that the decision spoke for itself.
Ms. Tantaros, a former co-host of “The Five,” could not be reached for comment. She was recently reported to be representing herself in the case.
A separate lawsuit filed by Ms. Tantaros in New York State Supreme Court in 2016 alleged that Mr. Ailes harassed her, and that other Fox News executives ignored her complaints and eventually forced her off the air. Among those named in that suit was Suzanne Scott, who on Thursday was named the new chief executive of Fox News; Ms. Scott has denied all wrongdoing.
Fox News denied Ms. Tantaros’s allegations in that lawsuit and maintained that the host was let go for violating a major part of her contract: She did not receive network approval for a book she wrote, titled “Tied Up in Knots: How Getting What We Wanted Made Women Miserable.”
A state judge ruled in 2017 that those claims should be sent to arbitration.
