Both of those shows currently air on Fox (a third, American Dad, aired on Fox for a decade before transitioning over to TBS) but over the weekend, MacFarlane sent out a tweet criticizing Fox News, and specifically host Tucker Carlson, for telling viewers to distrust anything aired on rival news networks like CNN or MSNBC. This wasn’t some vague subtweeting either. He couldn’t have been more explicit about how it makes him “embarrassed” to work for Fox.
The exception to that rule, apparently, is Family Guy and The Orville creator and star Seth MacFarlane.
