Grandmother died suddenly?
Didn’t his sister or half-sister die more suddenly right before she was about to give an interview to a newspaper reporter?
I don’t remember anything about the sister, but IIRC, the grandmother suddenly became ill when the campaign and questions about his birth were heating up. He went to see her in Hawaii and she died while he was there or right after he left. Just a few days before the election.
The whole thing was creepy/suspicious.
