This is the first I’ve heard of it, but here’s one of his infamous quotes:

"There is a trait in the Jewish character that does provoke animosity, maybe it’s a kind of lack of generosity towards non-Jews.

I mean, there’s always a reason why anti-anything crops up anywhere; even a stinker like Hitler didn’t just pick on them for no reason.”

His other quotes tend to be condemnation about specifically Israeli zionism and barbaric murder, buy i don’t have context as to whether he’s referring to palestine or not. Some people might have more sympathy for these statements these days, but a lot of his other quotes have to do with Jews controlling money and media, less defensible prejudice.
