Official documents are NOT just pieces of paper. They are part of a high-level government process with enormous financial impact for taxpayers.
Yes, it's called deliberate or purposeful destruction of evidence. If paper or electronic records are not "found" or don't match the "independently archived" material, it may be a perjury and/or a felony offense.
I just hope our elected reps and talk shows (hosts and guests) don't talk too much about this or make it a campaign issue - this is about the only reason for the Dems / libs to get excited about and come out to vote in November elections.
As the CIA has said---"they always leave a paper trail."
