Trump's sister is a judge. I'm guessing she's advising him on some things, as well as Levin.
Read an article about the siblings and it seems she's pretty darned smart, too.
I actually knew his older brother when I was a kid in the 70s. He worked at the neighborhood dock on Long Island Sound. He knew I was a Mets fan, and gave us tickets to the games on several occasions. The first time it happened, we were surprised to find ourselves seated in THE BEST seats in the house, in a box marked “Trump (Something).” I don’t think it was The Trump Organization yet because although Donald Trump’s name was pretty well known in the NY business circles, it had not yet become a household name.
BTW, even though his brother (Fred Trump, Jr.) was an extremely nice man, sadly, I don’t think he fit in with the rest of his family and ruined himself with drink. It killed him eventually. Rumor has it that that’s why Donald Trump does not drink at all.
