Well that would be a modern take, but since Trump seems to be a regressive I suggest one these methods:
Stoning, with rocks not weed
Beheading
Grilled Alive, what wine do you serve with human flesh
Pressed, the condemned is placed face down on a sharp rock, a heavy board is placed on their back, and then a heavy weight on the board.
Hacked to death by children
Flayed, that’s wear we get our pound of flesh
I’m sure that there are many more interesting ways. I personally vote for banishment to a deserted island. Trump all alone with only himself and no phone.
