If I were on the House committee questioning Mueller in public, this is something I would ask:

[pnwmom]

Is the 448 page report, with redactions, the full report you sent to Barr? Or was there an additional section or sections that Barr retained?

What questions would you like to ask?

[FBaggins]

1. The table of contents was from Mueller

And the intro refers to the overall structure of the report.

I don’t think Barr could hide other than by redaction.

[pnwmom]

2. How do we know there wasn't a second half with its own table of contents? n/t

[FBaggins]

7. That would require Mueller to have intended to hide it

Barr couldn’t do it.

[pnwmom]

8. Maybe there was a counter-intelligence report. Congress needs to know if such a report exists,

so that they can request it. Even if it can't be made public, it can be shared with Congress, at least to those with proper clearance.

3. I'd ask "Did Barr end your work before you were done?"...nt

[pnwmom]

4. Yes! And the follow up, if Mueller said "no."

Why did you wrap it up when you did? Were you concerned about the new Attorney General ending your work, or is this when you would have ended it anyway?

5. "Do you believe

any state vote tabulators were hacked in 2016--with or without insider assistance--to modify vote totals enough to change the outcome of any race on the state's ballot? How concerned are you about that possibly happening in the future?"

[spanone]

6. Did barr's summary match yours?

[Karadeniz]

9. How many administrations have you worked under. (Pretend Mueller says five.)

All right, on a scale of one as best to five as worst, how would you personally rate this administration with respect to...
...corruption
...living up to the oath of office
...respecting the rule of law
...transparency

10. Did you procure Trumps tax returns?
