I have a feeling that the NSA picked up conversations with foreign agents that lead to American nationals discussing election fraud. They then went to the FISA court with a warrant to spy on Americans and have ACTUAL evidence. That would be so glorious.
He is behind it because of all the other illegal things he and his administration did. To them this is a small time operation compared to what will come out in POTUS second term. They had one shot to take him down and now it's crumbling because of our overwhelming votes for POTUS that their system couldn't handle.
I've been thinking he may have had spies in some of these areas so he is well aware of what is and was going to happen. These spies have been collecting evidence and once it hits the courts he'll drop a big dump of emails, videos, phone conversations as evidence and destroy them. Hope I'm right.
I'm not so sure this is Parler doing it intentional. We use a web and spam filter at work and the past week thedonald.win has been giving a pop up that the site may contain profane and controversial opinions, you then have to click a button to continue to the site. It's maintained by the company, M$, and the only option we have is to automatically block or give the warning message. I know this as I'm in IT but we have no way of flagging a site as valid.
If it wasn't clear before it certainly is now since they keep using this supposed capital riot coup for everything that they planned the event in order to use it as an excuse for what they are doing.
