 This is what the Constitution teaches. This is what the founders intended. The whole balance of powers is so that neither the executive, the legislative, or the judicial gets an undue upper hand. They all have a certain space that is carved out for them. And one of the spaces carved out for a president is we're not going to have overambitious jack-wagon district attorneys or attorneys general in some hostile state come after a guy and dog him for something he did in the conduct of his duties today.
