"Buzzfeed, I salute you," Malkin noted on Twitter, noting that the site effectively exposed Trump as a "clown."
Malkin scoffed at Trump for including Maureen Dowd and Bob Schieffer among his favorite journalists.

"What drives Clown Trump?" she asked. "NOT conservative principles, but a vainglorious desire for constant validation."
In return, Trump has called Malkin a "dummy" and a "loser" who was "born stupid."
