Not necessarily inconvenient; it afforded him “cover” to visit her and dispose of any documents (birth certificates, passports, etc) that would have been in the closet, attic, etc.
That's what it was all about. Getting rid of the documents. Though it does beg the question of why someone else (In the Dem Machine) couldn't have done it. There are plenty of Democrat
Stazi dirty trick people who could have taken care of a few documents. I think the problem was still to convince the HI government to go along with it, and that required a personal appearance.
Yeah, I know: tin-foil hat stuff. But the whole incident was so unnatural. To "go see your dying grandma", and then not go see her two day when you arrive. Bizarre.
