The Clinton's Uranium deal with Rosatom is a nice example of how this works; of course you can't just give politicians piles of money, it needs to come with a bedtime story for the voters.
A Canadian company owned uranium reserves and wanted to sell the ownership of them to Rosatom. Not the physical resources, which cannot leave the country, just the ownership.
This still requires government oversight, so 8 different agencies had to sign off on it. All agencies did, including the state department. Hillary was not involved in the decision to approve the sale, apart from in charge of one of the many departments overseeing it.
You can safely ignore anyone who claims that the Clintons took money from anyone if they're claiming that money donated to their charity ends up in their pockets. They don't know what they're talking about.
Basically everyone outside of their little communist bubble know what the Clintons are all about. More power, at any cost. But it's ending any second now, mark my words. The stuff that's been trickling out so far is the tip of the iceberg.
