re: #258 Dr Lizardo

Has the SCOTUS ever ruled on whether or not a sitting President could be indicted?

AFAIK, they never have. That particular question was dodged by Nixon’s resignation.

No, they haven’t. I do know that the Kentucky Supreme Court held that the Governor cannot be indicted for a state criminal offense while he is in office, but of course that has no precedential value in regards to the President.
