His critics have used a lot of adjectives to describe Donald Trump: outrageous, flamboyant, pompous, thin-skinned, erratic, egocentric and paranoid, for starters.
But maybe it's time to use another word: "crazy." Not "crazy" as in wild and funny, but "crazy" as in mentally unstable. Given his bizarre behavior, it's a question more and more people are asking these days.
One thing's for sure, we know Trump's a pathological liar. He lies with every breath. He lies so often about so many things he makes "Lyin' Ted" look like a truth-teller. Look at his contradictory statements about Vladimir Putin.
Back in 2014, he bragged: "I was in Moscow recently and I spoke, indirectly and directly, with President Putin, who could not have been nicer." Last November, he claimed he "got to know Putin very well because we were both on '60 Minutes.'" But this week, he told reporters: "I never met Putin. I don't know who Putin is."
