Fox News employees and viewers were saddened on Thursday morning to learn of the death of the news channel’s founder and former CEO, Roger Ailes.

His wife Elizabeth broke the news by issuing the following statement:

I am profoundly sad and heartbroken to report that my husband, Roger Ailes, passed away this morning. Roger was a loving husband to me, to his son Zachary, and a loyal friend to many. He was also a patriot, profoundly grateful to live in a country that gave him so much opportunity to work hard, to rise—and to give back. During a career that stretched over more than five decades, his work in entertainment, in politics, and in news affected the lives of many millions. And so even as we mourn his death, we celebrate his life…

Before starting Fox, ailes was a media consultant for Richard Nixon, Ronald Reagan, and George H.W. Bush. He also assisted Rudy Guliani in his first mayoral campaign and helped Donald Trump with his debate preparation in 2016.

Our thoughts and prayers go out to his family.
