Roger Ailes might be the 'Loudest Voice in the Room" but Bill O'Reilly would have to come into a close second.

The media industry is obsessing on Gabriel Sherman's new book about Fox News and it's boss Roger Ailes. 

Sherman shares a number of stories about Ailes and his ruling of Fox News with and iron first, but sometimes the book branches off to others at FNC.

Like Bill O'Reilly.

In the book, Sherman writes that the top Fox News anchor grew so enraged at a female producer after a botched segment in 2003 that, in order to defuse the situation, “a senior Fox executive” intervened and escorted the crying producer out of News Corp’s Midtown headquarters.

“After one taping, he stormed toward his staff’s cubicles and tore into a young female producer, whom he blamed for botching a segment,” Sherman writes in Loudest Voice, which until today had been under a strict press embargo. “Staffers watched in shock as O’Reilly, easily a foot taller than the woman, started yelling and slamming his fist down on a shelf.”

“He got really close and in her face,” an onlooker told Sherman; “She was scared he was going to hit her,” said another. (The name of the producer is not revealed.)

Eventually O’Reilly vanished, after which “a senior Fox executive was called in and escorted the woman, in tears, out of the building to calm her down.” The famously vindictive anchor never apologized.
