According to The Times, Uranium One's involvement with the Clintons stretches back to 2005, when former President Bill Clinton accompanied Canadian mining financier Frank Giustra to Kazakhstan, where they met with authoritarian president Nursultan Nazarbayev. Going against American foreign policy at the time, Bill Clinton expressed support for Nazarbayev's bid to lead an international elections monitoring group.
Soon after, Giustra's company, UrAsia Energy (the predecessor to Uranium One) won stakes in three uranium mines controlled by Kazakhstan's state-run uranium agency. Months after the deal, Giustra reportedly donated $31.3 million to Clinton's foundation.
A source with knowledge of the Clintons' fundraising pointed out to The Times that people donate because they hope that money will buy influence. The source said: "Why do you think they are doing it — because they love them?"
