Chairman and CEO of Fox News Roger Ailes is resigning, and 21st Century Fox owner Rupert Murdoch Rupert Murdoch is now the acting Chairman and CEO, following a lawsuit by former host Gretchen Carlson and several allegations of sexual harassment.

In a letter posted to the Drudge Report, Ailes wrote:

“I am proud that we have built Fox News and Fox Business Channels into powerful and lucrative news organizations that inform our audience and reward our shareholders. I take particular pride in the role that I have played advancing the careers of the many women I have promoted to executive and on-air positions. Many of these talented journalists have deservedly become household names known for their intelligence and strength, whether reporting the news, fair and balanced, and offering exciting opinions on our opinion programs.”

Rupert Murdoch released this statement:

“Roger Ailes has made a remarkable contribution to our company and our country. Roger shared my vision of a great and independent television organization and executed it brilliantly over 20 great years.

Fox News has given voice to those who were ignored by the traditional networks and has been one of the great commercial success stories of modern media.

It is always difficult to create a channel or a publication from the ground up and against seemingly entrenched monopolies. To lead a flourishing news channel, and to build Fox Business, Roger has defied the odds.

His grasp of policy and his ability to make profoundly important issues accessible to a broader audience stand in stark contrast to the self-serving elitism that characterizes far too much of the media.

I am personally committed to ensuring that Fox News remains a distinctive, powerful voice. Our nation needs a robust Fox News to resonate from every corner of the country.

To ensure continuity of all that is best about Fox News and what it stands for, I will take over as Chairman and acting CEO, with the support of our existing management team under Bill Shine, Jay Wallace and Mark Kranz.”
