For those who are anxious about the effect of Presidential immunity for official acts, I thought it might be helpful to link to the DOJ's manual for prosecuting bribery crimes against Congressbeings. The majority's description of how immunity will work, at least for the "core" constitutional functions, operates pretty much like the current immunity that Congresscritters have under the Speech and Debate Clause.

Under that Clause, legislators are absolutely immune from civil or criminal prosecution for actions taken in furtherance of their legislative functions. That's not quite as broad as "official acts," but it covers a lot of what a Congresscreature does.

Yet Congressfolks can still be prosecuted for taking bribes in exchange for undertaking official acts, like voting a certain way or defending/attacking in their floor speeches. The Speech and Debate Clause creates some hoops that DOJ has to go through in prosecuting these crimes, but it doesn't foreclose it.

The immunity that legislators enjoy doesn't mean Congressbeings are "above the law," and hasn't led to a horde of them selling their votes for cash (or gold bars, an exception that proves the rule) - much less exchanging them for contract murders. They've been immune from criminal prosecution for most of their official acts for centuries, and we've managed to put them in jail when they break bad.
