Could you speak English please?
It seems tendentiously silly to say executive privilege allows a president to prevent a Senate deciding whether to remove that president from office from hearing the witnesses it wants to hear.
Does anyone here think that the constitution authorizes the President of the United States to use executive privilege to prevent the Senate from conducting its impeachment trial of that president as it wishes to? If so, why? (I assume it goes without saying that Bill Clinton, or Barack Obama, or any future president could use executive privilege in the same way people here think it can be used by President Trump.)
It seems to me that Mr. Bolton could refuse to testify if he wished (perhaps not without consequences if he were subpoenaed), but the president cannot prohibit him from doing so.
Or am I misinterpreting the claim being made here?
