There are just three simple yes-or-no questions Congress should ask Robert Mueller:
Mr. Mueller, the president said your report found, in his words, “no collusion, no obstruction, complete and total exoneration.”
First, did your report find there was no collusion?
Second, did your report find there was no obstruction?
Third, did your report give the president complete and total exoneration?
That’s it. That’s the ballgame. It makes no difference if there are 20 questioners or two when Mr. Mueller appears before two House committees on Wednesday. All of this speculation about whether Mr. Mueller will go beyond the four corners of his report is largely a waste of time, with one asterisk. The report itself is deeply damning to Mr. Trump, elevating him to the rare president who has been credibly documented as committing federal crimes while sitting in office.
