You do know that Mary Trump has a PhD and is a practicing psychologist. Knowing the family history plus her educational credentials she is an excellent position to talk about Trump's cognitive issues.
Her uncle sold her family down the river, fool. Because that's who is is. It's what he does. Ask anyone who didn't bow down to him.
His older brother, Mary's dad, drank himself to death to escape their father and young Donald. "Fred Jr., named for their father Fred Trump Sr., died in 1982 at the age of 41 after a long battle with alcoholism. Trump told the Post, "I do regret having put pressure on him" to run the family business, adding, "I think the mistake that we made was we assumed that everybody would like it. That would be the biggest mistake," he said of both he and his father." But then, Donald went after Mary's disabled nephew as punishment for trying to get what was rightfully theirs so Donald would not be able to use the life of the boy, his medical bills, as leverage against them.
