I understand that in theory but what is to stop an impeached president from citing this decision as the reason why an impeachment is not valid? I guess I’m asking the extent to which this muddies the waters of the remedy.
Would a drone strike against Senators or Congresspersons calling for impeachment, who also happened for completely unrelated reasons to be a Clear and Present Danger to the US, be unprosecutable?
Might such immunity affect whether a Senator would support conviction?
