It was pure Trump and his critics are hot to portray it as the desecration of a place where decent Presidents dare not tread. There he is, for over an hour, in front of the Department of Justice sign, trashing his predecessors for weaponizing the justice system. He’s out in the open, speaking his mind. Biden — we couldn’t even tell if he had a mind.

Here’s an example of the anti-Trump take on the speech: “Trump calls his opponents ‘scum’ and lawbreakers in bellicose speech at Justice Department/For more than an hour, he delivered an insult-laden speech that shattered the traditional notion of DOJ independence” (Politico): “It was, even by Trump’s standards, a stunning show of disregard for decades of tradition observed by his predecessors, who worried about politicizing or appearing to exert too much control over the nation’s most powerful law enforcement agency. Trump, instead, called himself the ‘chief law enforcement officer in our country’ and accused the DOJ’s prior leadership of doing ‘everything within their power to prevent’ him from becoming the president.”
Key word: “appearing.”
