Last summer, as it wrapped up multiple settlements after the Roger Ailes sexual harassment scandal, Fox News and its parent company, 21st Century Fox, were trying hard to end the ugliest chapter in its 20-year history.

The downfall of Ailes, the former chairman and chief executive, had exposed a newsroom culture that many women there called hostile and demeaning. 21st Century Fox ordered an internal investigation and stated publicly that “behavior that disrespects women” would not be tolerated.

Nearly eight months later, the company finds itself still dealing with fallout from that crisis. In late February, 21st Century Fox reached a settlement worth more than $2.5 million with a former Fox News contributor who reported that she was sexually assaulted by an executive at company headquarters two years ago, according to people briefed on the agreement.

The contributor, Tamara N. Holder, has said that the network executive tried to force her to perform oral sex on him in February 2015 when the two were alone in his office, according to interviews with four people briefed on her account, and documents that detail her claims. Holder did not immediately report the episode to the company or the police, fearing that doing so would ruin her career, interviews and documents show.

Holder reported her allegations to Fox News last fall. The network investigated her claims, and the executive, Francisco Cortes, the vice president for Fox News Latino, was terminated, according to two people familiar with the matter. Holder left Fox News after her contract expired on January 1, 2017.

Jay Sanchez, a lawyer for Cortes, said Wednesday night in an email: “I am presently considering Mr. Cortes’ legal options.” Multiple attempts to reach Cortes by phone, by email, on social media and in person for comment were unsuccessful.

In a rare public disclosure on Wednesday, Fox News released a joint statement with Holder saying that in September 2016 she “reported an incident of sexual assault at Fox News headquarters from the prior year.”

“Immediately after Ms. Holder notified Fox News of the alleged incident, the company promptly investigated the matter and took decisive action, for which Ms. Holder thanks the network,” the statement continued. “Fox News is grateful to Ms. Holder for her many contributions during her tenure at the network and wishes her continued success.”

In an email, Holder said: “Yes, I was sexually assaulted. Immediately after I told the company where I worked about the incident, it promptly investigated the matter and took action, which I appreciate.”

In the months since Ailes’ departure, 21st Century Fox has struck agreements with several women who made sexual harassment complaints about Ailes and others at the network. They include a $20 million settlement with Gretchen Carlson, whose lawsuit against Ailes in July led to his ouster; a deal with Juliet Huddy, a longtime Fox News personality who made sexual harassment claims against the network’s top-rated host, Bill O’Reilly; and now the agreement with Holder, who had been a legal and political analyst at Fox News since 2010.

Ailes and O’Reilly have denied the sexual harassment claims against them.
