that was in 2011. donald trump continued to attack me in 2011. and for years after that. because i was the first and for a very long time the only person calling donald trump a liar because of his relentless lying about president obama's birth certificate. i used twitter to invite donald trump onto this program knowing that he would refuse because he would only do television interviews that he believed he could control and so our exchanges were limited to twitter. in december of 2011 he said that i was not long for tv and he has a face made for radio. in 2012 he called me the dumbest political commentator on television, said i will soon be thrown off the air. he called me too stupid, the dumbest man on tv, a very dumb guy, and a fool. but he never called me a dog. why didn't he go all the way with me? why did he stop far short of calling me an animal, a dog?
