Roger Ailes Reportedly Under Increasing Pressure to Leave Fox News

Amid speculation that Fox News Chairman Roger Ailes is under increasing pressure to leave the cable network amid sexual harassment claims, Fox News' parent company 21st Century Fox insisted today that Ailes remained "at work."

Two sources told New York magazine Tuesday that Ailes had been given until Aug. 1 to leave his position at the company, following allegations of sexual harassment from former Fox News anchorwoman Gretchen Carlson. The Wall Street Journal, a publication that was part of the same company as 21st Century Fox until mid-2013, likewise reported that he was in negotiations to exit the network.

A spokesman for 21st Century Fox issued a statement saying: "Roger is at work. The review is ongoing. And the only agreement that is in place is his existing employment agreement."

Carlson, a mainstay of the network for 11 years, left Fox News on June 23 and shortly afterward filed a lawsuit against her former boss. In it, she alleges that Ailes had "sabotaged" her career after she "refused his sexual advances," and that her job was terminated in retaliation for rebuffing him and complaining to him about sexual harassment.

In a video posted to Twitter Tuesday, Carlson said she wants "to support all women who have been victims of sexual harassment" and said that "it's so important that we will not be silenced."

Fox News and Ailes have denied Carlson's allegations.

"Gretchen Carlson's allegations are false. This is a retaliatory suit for the network's decision not to renew her contract, which was due to the fact that her disappointingly low ratings were dragging down the afternoon lineup. When Fox News did not commence any negotiations to renew her contract, Ms. Carlson became aware that her career with the network was likely over and conveniently began to pursue a lawsuit."
