Reporters, maybe, though some have already managed to move on to other networks.
But c'mon, you aren't ever going to see Steve Doocy or Brian Kilmeade on Today or Good Morning America or whatever CBS's morning show is called.
And you won't see Kimberley Guilfoyle or Greg Gutfeld on CNN or MSNBC, either.
All of the people you mention will certainly move on eventually to other MSM jobs, except maybe Gutfeld who might end up with his own media company of some sort.
