What prompted his "not that it matters" tweet?

Here's the tweet:



And here's what must have prompted it:

A memo has been turned over to special counsel Robert Mueller detailing a claim that Donald Trump asked for the Russia investigation to be officially cited in the firing of FBI director James Comey last year.

  The Guardian

What a fucking idiot.

The former acting F.B.I. director, Andrew G. McCabe, wrote a confidential memo last spring recounting a conversation that offered significant behind-the-scenes details on the firing of Mr. McCabe’s predecessor, James B. Comey, according to several people familiar with the discussion.

[...]

In the document, whose contents have not been previously reported, Mr. McCabe described a conversation at the Justice Department with the deputy attorney general, Rod J. Rosenstein, in the chaotic days last May after Mr. Comey’s abrupt firing. Mr. Rosenstein played a key role in the dismissal, writing a memo that rebuked Mr. Comey over his handling of an investigation into Hillary Clinton.

But in the meeting at the Justice Department, Mr. Rosenstein added a new detail: He said the president had originally asked him to reference Russia in his memo, the people familiar with the conversation said. Mr. Rosenstein did not elaborate on what Mr. Trump had wanted him to say.

So that's what Rosenstein edited out. I recall at the time that it was reported he edited Trump's memo, but no one said what he changed. I figured he edited out some nasty comments about Comey.

This is rich.

To Mr. McCabe, that seemed like possible evidence that Mr. Comey’s firing was actually related to the F.B.I.’s investigation into the Trump campaign’s ties to Russia, and that Mr. Rosenstein helped provide a cover story by writing about the Clinton investigation.

"Seemed like possible evidence." Yeah, I guess it does. Mr. Mueller thinks so, too.

Mr. Rosenstein gave Mr. McCabe a copy of a draft firing letter that Mr. Trump had written, according to two people familiar with the conversation. Mr. McCabe later gave that letter, and his memos, to Mr. Mueller.

[...]

One person who was briefed on Mr. Rosenstein’s conversation with the president said Mr. Trump had simply wanted Mr. Rosenstein to mention that he was not personally under investigation in the Russia inquiry.

Another nice try for cover. Alas, you can't protect him from himself.

Mr. Rosenstein said it was unnecessary and did not include such a reference. Mr. Trump ultimately said it himself when announcing the firing.

[...]

“And in fact, when I decided to just do it, I said to myself, I said, ‘You know, this Russia thing with Trump and Russia is a made-up story,’” Mr. Trump said. “It’s an excuse by the Democrats for having lost an election that they should have won.”

Mr. Trump also told Russian diplomats in the Oval Office that firing Mr. Comey had relieved “great pressure” that he had faced because of Russia.

I don't know why Trump didn't take the opportunity to badmouth McCabe and the Times in his tweet. At least I'm surprised he didn't remind us McCabe was fired for not being forthright about some things, so, you know, why should we believe anything he wrote in a memo? I'm guessing he's still in shock about this memo getting leaked and, being guilty, didn't wait to settle down with a plan before firing off a tweet. Not that it matters.

I know another narcissist liar who uses that phrase when lying while also feeling guilty. I wonder if that's common.

...but hey, do what you want...you will anyway.
