Yeeep, staging a coup can be considered an 'official act' by the President. In the side notes, they also said directing the DoJ to arrest your political enemies and ordering the military to do literally anything you want are also official acts that you can't be arrested for.
Considering its an explicitly stated Trump goal....next year at the earliest depending on how the election goes. Or the next time any Rep wins. Naturally the ideal democracy is one where if you lose one election is over >.>
