You're just prattling on repeating the same points over and over again.
Another point repeated. If you want to write a letter to the OLC outlining why their rationale (that indicting a sitting president is unconstitutional) is wrong, you are free to do so. I'm sure they'll be thoroughly convinced by a Vox article.It makes no sense because the OLC and the Justice Department are not bodies recognized by the Constitution. So no, the policy literally has nothing to do with the Constitution aside from the fact that this is their interpretation of the principal-agent problem inherent to having a Justice department in the Executive branch. I.e., the justice department is under the President's chain of command, and he can theoretically order all of this to go away cording to Keith from Princeton.
