let's do the seal team six hypo. president orders st6 to assassinate a political rival bc rival is a threat to national security. possible this is absolutely immune under pres's commander in chief power. if it's not, then it gets presumptive immunity (which may be absolute anyway)
I'm sure impeachment will be an effective remedy against a President who {checks notes} is known to kill someone who identifies themselves as his political opponent. I'm sure lots of people will vote to remove him, among the surviving Senators.
