Fox News’ Dana Perino advised Democrats who appear on Fox News to “pull your punches” and refrain from attacking the network or its hosts.

“If you plan to come on Fox News just to take a shot at the network or the host, you’ll lose,” Perino, who was White House press secretary during the Bush administration, wrote in an op-ed for Fox News Thursday. “Taking shots at Fox News while on our air on [sic] makes you look small and is disrespectful to the audience that is tuned in and loyal to the channel.”
