Frank Giustra, a Canadian mining financier, wins a major uranium deal in Kazakhstan for his company, UrAsia, days after visiting the country with former President Bill Clinton.

UrAsia merges with a South African mining company and assumes the name Uranium One. In the next two months, the company expands into the United States.

Negotations begin for an investment in Uranium One by the Russian atomic energy agency, Rosatom.

Uranium One and former UrAsia investors make $8.65 million in donations to the Clinton Foundation. Uranium One investors stand to profit on a Rosatom deal.

Investors give millions more in donations to the Clinton Foundation.

Rosatom seeks majority ownership of Uranium One, pending approval by the Committee on Foreign Investment in the United States, of which the State Department is a member.

Rosatom says it does not plan to increase its stake in Uranium One or to take the company private.
