I think its important to note that he is being tried for bank fraud and not anything to do with espionage.
The trial, then, is itself a coverup.
The bank fraud evidence was all the solid evidence L/E had at the time they nailed him at the airport. What started in 2016
as a sketchy investigation into House equipment and data theft then evolved into falsely obtaining home equity loans
and wire-transferring $300,000 to Pakistan.
The espionage case is unfolding as we type.
