House intelligence Committee Chairman Devin Nunes announces the congressional probe into the Russian Uranium One deal. As described, the initial part of the probe will be to discover if there was actually an ongoing FBI investigation into the company at the time the Obama administration gave the green light for the controversial purchase.
In order to answer that originating question the DOJ has released an FBI informant from their non disclosure agreement (NDA). If it is confirmed the FBI was actually conducting an investigation - the additional lines of probative value will encompass how the Committee on Foreign Investment in the United States (CFIUS) approved the purchase during an ongoing FBI investigation.
If the FBI was investigating, and if CFIUS approved the purchase despite the investigation, then it appears congress would move to the third probative point "why"? ...
