Two reasons:
1. If Clapper goes down, so is Obama.
2. The first person to cooperate or goes to the prosecutors gets the best deal.
Problem for Clapper is the DOJ already has all the evidence they need to take down all the plotters to overthrow the government.
Clapper didn’t implicate anybody. That’s wishful thinking. Clapper is saying that Obunga is an unspeakably wise and brave hero for ordering the investigation of the wicked Trump Campaign, and protecting us from the evil Russians. That will be the Rat claim, should this stuff ever go to trial.
Because Clapper is a snitch, and his snitching on Obama only proves how big of a leaker he’s been his whole career. He’s got diarrhea of the mouth.
Clapper will be first to die of an unexpected heart attack...
