My suggestion would be to ask the NSA to sweep through the communications captured in the DC area the night and the day following Trump’s victory in 2016. If only to review pen-register level information about calls made in those first 24 hours, as it dawned on the Obama Administration that they were not handing over the reins to a friendly successor. The setup of the Russia Hoax, the framing of Flynn, etc., were all hatched in the White House by angry and exiting Obama staff. However, I would be willing to bet that a significant amount of documents and data were hastily discarded that day, and that can be traced.
Maybe so!
