George Will delivers commentary on the departure of Bill O'Reillyat FOX News in an appearance on CNBC. "Well, the question is, are they loyal to Bill O'Reilly or are they loyal to the FOX brand itself," Will said of O'Reilly viewers. "When Megyn Kelly left and they put Tucker Carlson in her slot nothing happened. The ratings stayed strong, and the viewers were happy. I have a feeling that Mr. O'Reilly is replaceable. As Charles de Gaulle said, the graveyards are full of indispensable men." You may recall, Bill O'Reilly and George Will entered a feud in late 2015 when the FOX News host called the then-FOX News contributor a "hack." In 2016, O'Reilly said he "destroyed" George Will. In December, O'Reilly said Will holds "personal animus" for Trump.
