1) Now that Mueller will testify, many are downplaying "expectations."

But there is an area where Dems can further expose wrongdoing by Trump and his cronies.

Dems can flesh out the ways that Trumpworld's obstruction *did* impede the investigation:

2) Former prosecutor @BarbMcQuade tells me that Democrats can ask Mueller many useful questions about what he was *prevented* from learning.

Trump refused to sit for an interview. What did Mueller want to learn from an interview that he could not?

@BarbMcQuade 3) As @BarbMcQuade points out to me, Democrats can also ask Mueller what he was prevented from learning about the Trump Tower meeting, by Don Jr.'s refusal to testify.

My interview with McQuade is in this piece:

@BarbMcQuade 4) I also talked to @RepAdamSchiff.

Schiff tells me Dems can ask Mueller about the *counterintelligence* part of the probe, which is still poorly understood.

And Dems can ask whether more was learned about Trump's talks over a Moscow project.
