There has virtually been no real investigations of the democrats and the Clintons.
I would have to write an article to go through all the possible avenues of these investigation issues.
The democrats only want to investigate Trump and Russia to get the spotlight off all of the democrat and Clinton issues.
They are using the Mohammad Ali Rope a dope. The Clinton and Obama Benghazi, and the private email server was not really investigated. We have strong evidence on the Clinton Foundation being quid pro quo with many foreign nations including Russia and China. Podesta and his brother have serious ties to the Russians.
The Clinton Foundation unlike the huge Banking and Financial institutions are not too big to investigate.
So my answer to your question is Definitely but not limited to China! .
