Quotations are Mueller’s. Basically he repeated and stressed the main points from the report.
I find it helpful to start with my own summary. So here goes.
“. . . they used sophisticated cyber technique to hack into computers and networks used by the Clinton campaign.”
At the same time this was happening, “a private Russian entity engaged in a social media operation . . .
The indictments alleged and other activities in our report describe efforts to interfere in our political system.
“Obstruction strikes at the core of the government’s efforts to find the truth and hold wrongdoers accountable.”
Vol II describes “the results and analysis of our investigation into obstruction by the president.”
[Yes, this clearly contradicts the “total exoneration” claim.]
“We did not, however, make a determination of whether the president committed a crime.”
OK, so why couldn’t Mueller make a determination of whether the president committed a crime?
The special counsel is bound by DOJ policy, so “charging the president with a crime was therefore not an option we could consider.”
💠it's permissible to investigate a sitting president so a record can be made while memories are fresh and documents available; and
💠the Constitution requires a process other than the criminal justice system . . .
[This means Congress—not the executive branch—decides whether the president committed wrongdoing. See this explainer👇 ]
Mueller thus concluded that “we would not reach a determination one way or the other about whether the president committed a crime.”
“Access to our underlying work product is being decided in a process that does not involve our office.”
[This means Congress can get the evidence through the courts without him.]
Mueller reiterated his central findings—that there were “multiple systematic efforts to interfere in our election, and that allegation deserves the attention of every American.”
Let’s examine Mueller's logic. He says if he could exonerate Trump of obstruction, he would. But he can't.
At the same time, he cannot conclude whether or not Trump did commit obstruction of justice.
In a weird roundabout hairsplitting way, Mueller said that Trump Obstructed Justice without actually saying it. [Well after all, he’s a lawyer.]
My first thought was that this will make it harder for Trump & pals to spin the narrative . . .
Well, after all, Trump’s entire "legal defense" is to torpedo truth itself.
End/ (except answering questions)
The DOJ doesn't "make" it unconstitutional, but because the Supreme Court hasn't taken a position on this, government officials are required to do what they believe is constitutional.
