No owner’s manual?
First, he does not own it, he rents it, by the consent of the governed.
Also, if their is a deed or title to the office, it should be held by the American people -—
And temporary residency only given to those who have documentation that they deserve it!
I agree “No owner’s manual?” He may not have a manual, but he does have a staff of hundreds who do have lots of manuals and advice and “expertise” and his staff is perhaps two to four times the size of the previous resident.
