When ever I hear about Trump getting bad advice Kushner's name always comes up. Basically I'm trying to figure out what he's done to deserved this criticism. All I know about is that he encouraged Trump not to get of Twitter when Parler was still good. While that is bad, its not enough to garner all the hate he gets among Trump supporters. So, my question is, what all has he done?

I can do the research myself, but I'm just looking for a starting point.
