To say the U.S. government approved a Russian take over of 20% of U.S. uranium production is a misrepresentation of the facts. The deal was also approved by the U.S. Nuclear Regulatory Commission and the Utah state nuclear regulatory body.
It’s also worth noting that U.S. prohibits the export of nuclear materials like to a country like Russia. As a result, no uranium involved in this deal was ever transferred out of the United States.
Furthermore, although the timing of all the transactions may appear suspicious, there simply is no evidence of a quid pro quo.
