Some experts think that the President has the power to pardon himself, some don't. But virtually everyone agrees that even if the President has that power he should not exercise it; Giuliani has said it would lead to impeachment, and even Trump himself has said that he has no need to pardon himself.
If everyone agrees that "self-pardon" should not be a thing, shouldn't that then be a rare case where a constitutional amendment to clarify the issue once and for all could be easy to push through?
The amendment could be something like this: "The Power to grant Reprieves and Pardons for Offences against the United States granted to the President shall not apply to Offences committed by the President himself."
Would that mean that if I'm elected president I can never be pardoned?
