Which is why the need to subpoena him back to congress and force testimony, risk purgery or destruction of his character but forcing his admission, he cannot refuse to answer as he cannot self indriminate.
Taking the 5th is not applicable becuase he is pardoned, so he must answer or deny and the denial will now be purgery and chargable.
Good point.
A valid point. But I could see the Democrats saying that with all the Republican hubbub about POTATUS not actually signing the pardons, the question arises whether or not his pardon is legitimate. And that needs to be litigated to determine whether or not he got a valid pardon. In case it is determined that his pardon is not legitimate then we must protect his right against self-incrimination! So have patience, the courts will determine this matter eventually. Someday. Over the rainbow.
