He has no choice tomorrow but to stay with the script he wrote out in his "preview" today. If he strays, he will probably be brought up on charges of perjury by one side or the other.
Even if Trump asked him to, "take it easy on Flynn", it's not obstruction of justice any more than it was when Wild Bill met with the former Attorney General on an airport tarmac.
Unless Comey is willing to say that Trump threatened him in some way with blackmail, this is going to end up being much ado about nothing. If he does say that Trump threatened him, then he will be guilty himself of not reporting a crime.
This little democrat show is payback for the Hillary e-mail case. It will end the same way. None of these congressmen and women have a clean enough closet to take down anyone else and they all know it.
Trump skates on this and the dems find another rabbit hole to go down. None of the personal attacks are working. I can't believe they're keeping it up. Making themselves look like spoiled little children and it will cost them in 2018.
Comey goes away tomorrow and he's just lucky he's not testifying against Bill or Hillary.
