A small number of Fox News employees who were known for known for having ties to former network chief Roger Ailes have quietly left the cable-news outlet in recent days.

Brigette Boyle and Nikole King, the senior vice president of recruitment for Fox News and Fox Business, and the senior vice president of business development and mobile for Fox News, respectively, have departed, a spokesperson for the 21st Century Fox-owned unit confirmed Friday. A contract for Bo Dietl, a celebrated private detective who has been an on-air contributor at Fox News, recently ended, the spokesperson said.

News of the departures of Boyle and King were previously reported by CNN. The ending of Dietl’s contract was reported previously by New York magazine. The executives had long worked with Ailes.

The spokesperson characterized Boyle’s departure as “mutual and amicable,” and noted that King’s job had been eliminated as part of corporate streamlining. Dietl is not at present scheduled to make new appearances at Fox News or Fox Business, the spokesperson said.

The Fox News ranks have been under scrutiny since the departure of Ailes, long viewed as the architect of the strategy that transformed Fox News Channel from a start-up operation in 1996 to the nation’s most-watched cable-news outlet in 2016. Gretchen Carlson, a Fox News anchor who left the network earlier this summer, accused Ailes of sexual harassment, and he left the company in the wake of an internal investigation into the matter started by 21st Century Fox. Ailes has denied the allegations made against him by Carlson as well as others that have emerged as a result of the probe and press inquiries.
