My guess would be that Trump asks them if they'll turn over all the documents and they both say "no".
And when they say "no" Trump proceeds to sign the order right in front of them compelling them to comply or be held in contempt within days.
I don't think he'll fire anyone and he'll let the evidence speak for itself once the IG report is cleared by DOJ for release and it'll become apparent to all that Trump is within his right after being set-up by the BHO DOJ and many others.
You would think that RR would have no say within DOJ and the real authority is with Sessions.
Time for the silent executioner to step up.
