Roger Ailes, the Chairman and CEO of the Fox News Channel, will appear on ABC’s “This Week” on the roundtable segment. He will be joined by George Will, Arianna Huffington and Paul Krugman, in what could be one of the more interesting Sunday morning shows in recent history.

I’m racking my brain, but I cannot recall Ailes ever giving a public appearance of this nature. He’s much more of a string-puller behind the scenes. Perhaps Barbara Walters, this week’s substitute host for the departed George Stephanopoulos lured him into the spotlight. Walters and Ailes are reportedly friends.

Ailes was the recent subject of a long feature in the New York Times, which included some not-so-flattering information about his personal paranoia:

As powerful as he is within the News Corporation, Mr. Ailes remains a spectral presence outside the Fox News offices. National security had long been a preoccupation of Fox News, and it was clear in the interview that the 9/11 attacks had a profound effect on Mr. Ailes. They convinced him that he and his network could be terrorist targets [...]

His movements now are shadowed by a phalanx of corporate-provided security. He travels to and from work in a miniature convoy of two sport utility vehicles. A camera on his desk displays the comings and goings outside his office, where he usually keeps the blinds drawn.

Mr. Ailes said he received frequent threats over the years, but his concerns for the safety of his family were heightened by an incident at his New Jersey home after the 9/11 attacks. There was an intruder on his property, but no arrest was made. In Putnam County, he has bought several properties surrounding his home. A sign outside his house shows an illustration of a gun and advises visitors that it is under video surveillance.

It’s unclear how much security will be required outside the Newseum, where “This Week” is taped, on Sunday.
