Trump is calling Comey a liar because to Trump, all criticism is a lie - WaPo opinion (limited access). I thought both the headline and article were spot on.
a venal mix of hypocrisy and desperate attempts to convince Americans that the former FBI director is a liar — that up is down, and down is up.
Indeed, Trump and his sycophants are such inveterate liars that using the "I'm rubber, you're glue" analysis is almost a proof of any proposition.
But to the Trumpist die-hards, any criticism is a provocation, no matter how plain and irrefutable its validity or veracity. The speaker does not matter, only that what the speaker is saying is oppositional. This is how the GOP performs the sort of moral contortions that led the party to create a website, lyincomey.com, with the explicit purpose of smearing the former FBI director, a registered Republican, ahead of publication of his book.
Like the, "I'm not a puppet, you're the puppet" claim in the debate, just assume that any aspersion cast upon another is a confession of the claimant to the proposition.
I was appalled, but unsurprised, when Sarah Sanders stood at the podium and hurled demonstrably false invective at yesterday's press conference like it was Twitter, and she were just a troll. Oh wait... She is. That she had scripted the response was either an admission that it was pure agitprop, or a signal to the press corps that she was forced to parrot Trump, "so you can't believe anything I'm saying." She literally had the demeanor of a prisoner of war being forced to read a manufactured confession into the camera. "Wink, wink - everything I'm saying should be applied to my boss..."
That is why I've been convinced from the outset that Trump was guilty of subversion and collusion. If he makes a claim it is invariably true that the opposite is reality. Just substitute "I'm" for whomever is the object of his attack. "
You'reI'm the puppet," "
he'sI'm a loser," "
Comey'sI'm a liar" try it yourself! - it's like a parlor game.
And, of course, "there is collusion".
