Malia Obama interned for Harvey Weinstein just a few months before he went from top of the world to candidate for spending the rest of his life in prison.
I strongly suspect Barack Obama decided to end Weinstein’s career even though he was a huge Dem donor and supporter. And it probably was because he did something to Malia, perhaps made a pass at her.
Weinstein was one of the most powerful men in Hollywood, but the Obamas are much higher up the food chain in the pecking order.
Harvey Weinstein apparently didn't proposition black women. It could be that he didn't prefer them. It could also be that black actresses used the race card to get their roles, not the casting couch.
