According to WikiLeaks founder Julian Assange, the emails — which are labeled as “Part I of the Podesta emails” — focus on Podesta’s “communications relating to nuclear energy, and media handling over donations to the Clinton Foundation from mining and nuclear interests.”

Donald Trump and others have accused Clinton of tying the State Department’s 2010 approval of a gradual Russian takeover of the U.S. company Uranium One to $145 million in donations to the Clinton Foundation.

The company was made up of land equal to about 20 percent of the U.S.’s uranium capacity, according to Oilprice.com — although experts note that the U.S. doesn’t actually produce a significant amount of the world’s uranium stock.

The State Department did not take unilateral action, but instead was one of a nine-agency review board, known as the Committee on Foreign Investment in the United States (CFIUS). The Clinton campaign has maintained that the then-secretary of State was not directly involved in the process.
