Thanks.Allow me: the Court held that there are three categories of immunity for a President's actions:
Absolute immunity for any acts that fall within the exclusive Constitutional purview of the President. Examples would be negotiating treaties and ordering the armed forces.
Presumptive immunity (but the presumption can be overcome upon a sufficient showing that the act was not "in his official capacity") for other acts where the President shares responsibility with Congress (i.e,, the President is subject to laws passed by Congress in how the Pres carries out the duties). For example, spending allocated funds for purposes outside the allocation.
No immunity for "purely private" conduct, even though he's the Pres. An example would be if he finds someone's wife at a state dinner attractive and "grabs her by the pussy."
There's about a gazillion shades of grey in there, and it will no doubt play out for the next several decades.
I always thought you folks would have mechanisms in place to keep a felon from running for president.
Big win for felons.
