Is
mal 
-railing against Hayes or Fox News or both? As to whether he or any other
MesSNBC talking head has ever been quoted on Fox, mockery of
MesSNBC talking heads is probably a staple for some Fox hosts, so I'm sure Hayes or MadCow or whomever are regularly quoted and mocked on Fox.
As for Hayes "quoting" Trump, Trump lives rent-free in
MesSNBC talking heads' heads - as well as in DUpipo heads - so "quoting" him is necessary for misrepresenting and lying about him.
