The only facts we need is that Rice did the unmasking, and Obama opened up the NSA spying files to hundreds (if not thousands) of new more deep state government officials, in the last days of his presidency. We already know there were many political appointees that were “burrowing” into career positions after the election.
Susan Rice was an advisor, not an investigator. It was not her job or in her purview to make this kind of decision on unmasking. There simply was no legitimate non-political purpose for someone in her position to be making that kind of directive.
