There really is a lot that Trump could do or direct get done—disclose information, respond to Congress and share requested information, etc. That he doesn’t suggest he sees more value in letting the DOJ and FBI twist in the wind, destroying whatever remaining credibility they have. Eventually, when the time is right, he’ll step in, and clean house. Well, that’s my hopeful side of the whole affair. The other is that he is leaving it to Sessions, who fell asleep, and the cockroaches are running wild because no one is watching.
The Presidlent is playing poker with his cards very close to his vest. He knows the agencies are corrupt at least through the first three levels, he knows the congress is a quagmire of conceit and treachery, if the leakers are truly about to be indicted, this will bust open the can of worms thence allowing the president to act with the extreme high ground.
