Is tRump's tweet about FBI investigation scope legally binding? Ian Bassin, yes.

Note to @FBI: whatever instructions White House staff gave you, the President’s tweet below is actually (no, really I’m not kidding) an order from the President. DOJ’s legal view is that a presidential order need not take any special form; if the president orders it, it counts.

Ruh-roh! Looks like tRump stepped in it by reacting too quickly to NBC's reporting, reversing the secret course the WH had originally intended by limiting the investigation's scope.

1. And there is still plenty of time for him to shoot his other foot by Monday

2. You may be right. I can see tRump getting out of hand all next week.

Oh, let him speak freely!

3. Yeah but will the FBI interpret it that way??

4. Time will tell, but here's what a former FBI Assistant Director of CI, said on 11th hour Friday.

@23:00 mins FBI can offer Judge Kavanaugh to take a polygraph. If he refuses it will be noted. "He may have a problem taking a polygraph exam."

Hmmm. As Chris Wray surely knows, Don McGahn has no legal authority to direct or limit the FBI's background check. This tweeter is the only officer in the Office of the POTUS with the power to do so. So his word--not McGahn's--governs.
