The government gave them plea deals because that's how you build a case against a higher level defendant. The government has convicted hundreds of people for Jan 6 and those case have not been overturned. Everything you wrote is wishful thinking. The facts are that multiple people have flipped on trump and have agreed to cooperate and or testify. That is not good for trump.
Aiding and abetting false statements and writings. Never ever put a lie inwriting and submit it to a court if you are a lawyer. But the bigger takeaway from this is that she's agreed to sit for interviews with prosecutors and has to testify in any trial they demand.
When jail becomes inevitable, those attitudes change quickly. Rudy is broke and now has Ellis giving interviews and having to testify against him. However, he may be a big enough fish that the prosecutors won't offer him a deal.
Lawyers DO NOT plead to felonies unless they are thoroughly fucked. She was thoroughly fucked. Now she has to testify for the government. It is NEVER good when someone takes a plea and flips. Ever.
