There is now a confirmation that the envelope contains indictments notice that was given to some of the invited guest at the funeral of former President Bush Sr. The notifications shows the US Military and the NSA are aware of the crimes and law violations including treason that these people have committed. The former President Bush Sr. was executed as the Military found him guilty of several crimes. They gave him a special treatment by offering him a very Confidential Judgment and not make it public to keep his legacy intact if he will cooperate, sign and admit all the crimes that he did in a Confession Letter.
This confirms that President Trump and the US Military are very serious about pursuing actions against the Deep State including the CIA. They have all the records of the Deep State: hard copy, digital, videos, phone calls and their electronic (email) activities.
