This statement from Trump back in the day pretty much says everything (excerpt from John O'Donnell's book "Trumped"):
Bigotry and stereotyping Jewish and black people in the same breath.Instantly, Donald was enthused. "Yeah, I never liked the guy. I don't think he knows what the f––– he's doing. My accountants up in New York are always complaining about him. He's not responsive. And isn't it funny, I've got black accountants at the Trump Castle and at Trump Plaza. Black guys counting my money! I hate it. The only kind of people I want counting my money are short guys that wear yarmulkes every day. Those are the kind of people I want counting my money. No one else."
I couldn't believe I was hearing this. But Donald went on, "Besides that, I've got to tell you something else. I think that the guy is lazy. And it's probably not his fault because laziness is a trait in blacks. It really is, I believe that. It's not something they can control. … Don't you agree?"
