Rod knows he's been exposed and now being scrutinized. He's boxed in. He's going to have to be on his best behavior.
Anything he tries to do will be evident.
His safe bet is to resign.
He will see that his NY buddies indict Trump on something and it doesn’t matter that it will go nowhere. Consider the slimeball testifying before the committee; he doesn’t care. He has dirt on the system and they will protect him.
“His safe bet is to resign.”
But a Trump supporter takes his seat with no senate approval if he resigns. He cannot have that. So he will try to force Trump to fire him so the senate can make Trump appoint another Mueller guy.
Now that the NYT, CNN etc know about the succession problem, pressure on Rosenstein will disappear from the news. And limbo in the DOJ continues ad infinitum.
