But according to a report in NPR, Rosen left amid "scrutiny of his behavior at the network".
Rosen, who is married with children, made "overt physical and sexual overtures", to three Fox News colleagues, according to the NPR report, which was based on interviews with eight of his former colleagues. Gretchen Carlson, a former Fox anchor, sued Mr. Ailes in 2016, saying he had forced her out after she refused his sexual advances.
Fox News confirmed Rosen's departure in December, but did not say why the 18-year employee left or announce it on air. Fox News in particular has struggled to deal with the fallout from sexual misconduct scandals.
The most recent incident took place last spring, when Rosen tried to kiss a young female reporter in an elevator.
Sexual harassment allegations have rocked major networks and publications across the industry, ushering in the abrupt ousters of high-profile media figures. Rosen also declined to comment to NPR.

Tharoor said, "Hindi has not been given the national language status in India". The minister replied back and said, "I am proud of all Indian languages".
Rosen's departure came during a period of increased scrutiny at companies around the country over the allegations of improper sexual behavior of men in positions of power.
Just last month, Fox's owner, Rupert Murdoch, told Sky News that there had been no further allegations at the company after Mr. Ailes was sacked in 2016 - and that those allegations were "largely political because we're conservative".
He added that the attention "was largely political because we are conservative". "There are really bad cases that people should be moved aside, and there are other things which probably amount to a bit of flirting, you know?" In exchange for her keeping the complaint private, NPR reported, Fox News and the producer, a foreign national, made a deal "that enabled her to extend her stay in the USA", in NPR's words.
