Elon, you need to get a court order, forcing this retiree to disclose all admin passwords for the operating system and databases. You cannot deny the POTUS the right to look at books and records and retiring does not absolve you from your responsibilities. What would you do Elon, if after you bought Twitter the admins changed all passwords then quit leaving everyone locked out of the systems? You would get a court order. This is not their property, it belongs to the American people. DOIT.
