You've done zero research about this, then.

A Canadian company owned uranium reserves and wanted to sell the ownership of them to Rosatom. Not the physical resources, which cannot leave the country, just the ownership.

This still requires government oversight, so 8 different agencies had to sign off on it. All agencies did, including the state department. Hillary was not involved in the decision to approve the sale, apart from in charge of one of the many departments overseeing it.
