wrt the clinton foundation i dont think the saudi money mattered. saudi arabia isnt just one thing. greenpeace could accept american money at the same time as people in the us were major backers of the ira too (and i dont think the foreign backing for isis is that clear or substantiel).
i also think the foundation was mostly just doing good work too.
the biggest problem imo was all the dodgy characters the clintons surrounded themselves with. there was a chelsea clinton email in the wikileaks stuff about how some pr/lobbying firm connected to the foundation, and paying bill clinton to be on their board, had been selling connections to the clintons.

huma abedin didnt have to get paid by the state department, the clinton foundation and teneo all at the same time either. the clintons always surrounded themselves with shady stuff like that and blurred the lines of what was appropriate.
