President Trump attacked Attorney General Jeff Sessions in several tweets Saturday morning, accusing him of lacking an understanding of what is going on “underneath his command position,” which is causing “real corruption” to go untouched.

“Jeff Sessions said he wouldn’t allow politics to influence him only because he doesn’t understand what is happening underneath his command position. Highly conflicted Bob Mueller and his gang of 17 Angry Dems are having a field day as real corruption goes untouched. No Collusion!” Trump tweeted.
