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.
