The headline on the website Pravda trumpeted: Russian Nuclear Energy Conquers the World." The article, in January 2013, detailed how the Russian atomic energy agency, Rosatom, [became] one of the world's largest uranium producers and brought Mr. Putin closer to his goal of controlling much of the global uranium supply chain. Major donors to the charitable endeavors of former President Bill Clinton and his family ... built, financed and eventually sold off to the Russians a company that would become known as Uranium One. Beyond mines in Kazakhstan that are among the most lucrative in the world, the sale gave the Russians control of one-fifth of all uranium production capacity in the United States. Uranium is considered a strategic asset. The deal had to be approved by ... United States government agencies. Among the agencies that eventually signed off was the State Department, then headed by Mr. Clinton's wife, Hillary Rodham Clinton. As the Russians gradually assumed control of Uranium One ... a flow of cash made its way to the Clinton Foundation. Uranium One's chairman used his family foundation to make four donations totaling $2.35 million. Those contributions were not publicly disclosed by the Clintons. Other people with ties to the company made donations as well. And shortly after the Russians announced their intention to acquire a majority stake in Uranium One, Mr. Clinton received $500,000 for a Moscow speech from a Russian investment bank with links to the Kremlin that was promoting Uranium One stock.
