Piers Morgan of CNN has been off the rails for days in the wake of the massacre at Sandy Hook, pressing forward his full-scale gun control agenda by steamrolling guests who disagree with him, and acting as though they don’t give a whit about the children murdered in Newtown, Connecticut. Today, he took that insanity to a whole new level.

It all began when he tweeted this:

After Morgan’s original tweet, Breitbart News simply posted the tweet with the headline, “Piers Morgan: ‘Of Course’ I’m ‘Gleeful Tragedy Happened.'” Morgan took the posting of his tweet as a personal insult; he claimed that the tweet was sarcastic. Breitbart News, of course, never argued that it was not. It let the tweet speak for itself.

But for Morgan, this was a grave indignity. And so he tweeted this:

Only one problem: Morgan never respected Andrew Breitbart. In fact, he called him “notoriously evil” on CNN. When Breitbart responded, “I don’t think you know me, Piers Morgan. I think we maybe spent eight seconds together,” Morgan shot back, “It was a long eight seconds.”

Those are not the words of knowledge and admiration. But then again, Morgan isn’t exactly known for his fidelity to the facts.
