This is the arrogance of intellectual ignorance(thinking you are smarter than you really are). This is also the arrogance of someone who believes that he and his minions are above the law.
A Constitution Law Professor who ignores the Constitution. Who usurps the powers of Congress and makes laws of his own and threatens the very people who are empowered to make laws that if they have the gall to force him to go by the rules that he will do whatever he wants and that he will find some way to get back at them.
These are the actions of a criminal, not a leader.
