Fox News sexual harassment inquiry is said to look at what others knew

Investigators looking into sexual harassment accusations against the former Fox News chairman Roger Ailes are also examining whether other executives knew of improper behavior by Mr. Ailes and failed to act on it, people briefed on the inquiry said Wednesday.

The investigation, focused narrowly on accusations against Mr. Ailes, has not broadened into a comprehensive look at the workplace culture at Fox News, these people said. But investigators will pursue information presented in interviews about others at the company who might have effectively enabled Mr. Ailes’s reported behavior.

The inquiry is continuing, these people said, with more current and former Fox News employees scheduled for interviews. As of last week, nearly 20 women had reported inappropriate behavior by Mr. Ailes, according to one of the people. The accounts, though unverified, led the leadership of 21st Century Fox, Fox News’s parent, to determine that Mr. Ailes could not stay on, this person said.
