Then you get to the Pence problem
as to why admitted and convicted Russian agent Manafort advocated tirelessly for him and finally arranged for Trump to be stranded in Indiana and meet with him.
Other problems there, with Flynn in particular.

Was it russian explosives experts who rigged the charges that dropped the twin towers? Did Pence and Trump arrange for the meetings? Did they give them a ride to the site?
Turn back the clock a few decades
And this gets handled as it did during the Cold War and The Human Q-tip sits in a block across the hallway from Aldrich Ames or The Rosenburgs.
Dennison might skate on all this, pleading unwittingness. Pence jumped on and steered response and policy.
