The twists keep on coming in the Roger Ailes Fox News scandal. The latest, as usual, comes from reporter Gabriel Sherman, who literally wrote the book on Ailes, and this time it's personal.

Sherman reported in New York Magazine that Ailes used Fox News money to fund public relations and surveillance campaigns against his enemies, including Sherman and other journalists. He also used company dollars to settle allegations of sexual harassment against him.

These shady dealings have been uncovered as Fox News executives pore through the network's financial records following Ailes's resignation. According to Sherman's sources at Fox, Ailes spent millions on these endeavors, but because Fox was bringing in more than a billion dollars in yearly profits, the amounts used personally by Ailes were almost negligible.

Ailes allegedly ran the operation out of an office dubbed "The Black Room" in a hidden corner of the News Corporation building. Among his surveillance targets were Sherman and Gawker journalists John Cook and Hamilton Nolan, all of whom covered Ailes in their reporting.

According to Sherman's sources, Ailes ordered private investigators to stalk Cook near his home and create a report on his actions that could be used against him in the media. He also had private detectives follow Sherman and his wife in 2012 while he was doing research for his biography of Ailes, The Loudest Voice in the Room. Joe Lindsley, who was editor of Ailes's hometown paper, The Putnam County News & Recorder, was also a target.
