It is almost reassuring to learn that Trump truly believes he is above the law.
Arguing that the law does not apply to the president is the essence of dictatorship. It's good to have that claim in black and white—reaffirmed by the even more bizarre claim by Rudy Giuliani that Trump could not merely fire James Comey but murder him and not be legally to called to account.
When Trump said that he could “stand in the middle of Fifth Avenue and shoot somebody” and not “lose any voters,” people dismissed that as hyperbole. It turns out that he meant it literally.
This is the stuff of impeachment and removal. If it isn't, we rapidly cease to be a democracy.
