To admit your wrong, hold yourself accountable, and accept whatever consequences that may come with it.
From the movie "Thinner"
Tadzu Lempke: Gives the "White man from town" a pie that can potentially lift the curse he has put on him. (*Note* The Pie doesn't actually "lift the curse per`se" but passes it along causing a vexing but rapid death to whoever consumes it)
White Man From Town: Accepts the pie
Tadzu Lempke: "Eat Your Own Pie" and die clean, die clean White man from town; die clean.
Trump could easily "Eat His Own Pie" and end all the investigations against him for the vile, wretched, and abhorrent existence he's defiled the planet with, but instead he will lie, deceive, and prevaricate to the very end until he's painted himself into a corner he has no way out of; in which case per the blessing and demand of the vast majority of the American peopleRobert Mueller will shove his pie down his throat.
However it happens you will Eat Your Own Pie Trump!

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
