There was clearly pay-to-play pay-offs between Vladimir Putin and Hillary Clinton starting in 2010 when Hillary got Putin billions in donations from 29 U.S. corporations who helped Putin build the Russian equivalent of Silicon Valley in a suburb of Moscow called Skolkovo.
Hillary also arranged, during the 2010 Nuclear Security Summit, to give Putin $400 million to build a uranium enrichment plant in Russia.

The Uranium One deal between Bill/Hillary and Putin netted a $145 million in pay-to-play pay-offs to the Clinton Foundation.

For Bill’s part in the treasonous sell-out of the entire American uranium market, Frank Guistra (Canadian owner of Uranium One) and Carlos Slim donated $200 million to the Clinton Guistra Sustainability Growth Initiative.

The lobbying firm APCO Worldwide, who did a great deal of free work for the Clinton Foundation while representing the Russians (Rosatom) in the Uranium One deal, filed reports recently that indicate that the Uranium One deal was worth over $30 billion.
