Whether or not President Trump pleads the Fifth, his attacks on the investigation will continue and he would use a subpoena as further evidence that Mueller is a prosecutor run amok. On Wednesday morning, he tweeted: “There was no Collusion (it is a Hoax) and there is no Obstruction of Justice (that is a setup & trap).”

Ty Cobb, a lawyer who has expressed discomfort with Trump’s attacks on Mueller’s probe, according to a source who spoke to CNN, is leaving the White House, and Trump is hiring Emmet Flood, who represented Bill Clinton during his impeachment process.

He will use the high drama of this encounter as political theater, making himself the victim and fueling the message that will be front and center in the midterm campaigns — elect a Democratic Congress and the next two years will be all about impeachment.
