Least anyone forget.  People who lie to gain positions from which they can undermine & back-stab people duly elected to office by Americans, are properly referred to as cowardly dishonorable "Traitors", not leakers.

And least some over-age adolescents claim - "But, but everyone always does it".
No. they don't.  Many women and men of honor have suffered and died keeping their words.

Obviously the Political Class and media thralls represented by the Bushes-Three, Obama, Romney, Hillary, McCain, Sanders Cruz, Pelosii , etc. Ilk couldn't drain that swamp. That's because if they undertook ending it, they would have risked illuminating how deeply in that swamp they live

That's another reason why America needed someone out side the swamp. Someone who hadn't done as Hillary did, and the Political Class mostly does - "go into politics" in high school and never leave.  A President who found such cowardly back-stabbing disgusting, not a handy "normal" part of "politics". As most Americans do.
