A basic fact about Donald Trump is that he never — absolutely never — admits doing anything wrong or apologizes for anything, no matter how egregious. Instead he attacks critics, viciously and often in blatantly dishonest ways.

He’s following this long-established pattern of behavior again today, responding to the arrest of his campaign manager for battery against reporter Michelle Fields by suggesting he may “press charges” against Fields.

Notice he says Fields “grabbed” him, but the image he posted does not show this. In fact, right after this tweet he posted another image that shows Fields didn’t “grab” him at all; but now he seems to be alleging she might have been trying to harm him.

Corey Lewandowski could have avoided being charged with battery by simply admitting he shouldn’t have grabbed Fields and apologizing at the very start. Instead he attacked her like his employer does, and accused her of lying — even though their own security surveillance video showed she was telling the truth.

If anything ends up destroying Donald Trump’s candidacy, it will be the overwhelming egomania and hubris that characterizes him and his entire staff.
