I wonder what's hidden in the files requested by Congress from the Department of Justice and the FBI? If I had to guess, I'd say they're not complimentary to many current high ranking officials, and those of the last administration.
It doesn't take much common sense to realize there is a strong effort to unseat the current President, and the slow walking of releasing information is not coincidental. Those part of the club called Washington D.C. know they're in world of trouble, and are hoping they can stall the release of information. When released, it will reveal criminal conspiracy, and deliberate acts of sedition.
