NOTABLE=
Very good articles written by J. E. Dyer, a retired naval officer. The first one was published at www.libertyunyeilding.com on May 13, 2020. I've numbered the articles because the most recent one I just spoke of leads with links to several older articles with very valuable information regarding the federal government's IT situation since back to 2012 and a little older.
These articles are about HOW the unmasking most likely was accomplished, by whom, and when it all probably started and then ramped up, and I mean, RAMPED UP. Had a lot to do with IT changes made and a switch to cloud computing during BO's Presidency. Be sure to read each link to get the whole picture.
I scanned the Notables to see if someone had already posted anything about this, but didn't find anything. My apologies if I overlooked it.
