The ABC article really is much better than the CNN one. It has actual quotes from the sealed order and goes into more details about the actual process, beyond what you're highlighting. The only thing that seems to really be missing from both is what the actual evidence is, as opposed to a description, which is bizarre if you're going to go so far as to make direct quotes of the order.

My guess on the evidence based on what's been in the news is a narrative that Trump was always aware that he had classified information since I believe the SC heard testimony that Trump oversaw the packing process of his documents. That or someone who did pack the documents said they knew they packed classified documents and told Trump as such.

He's a popular politician who easily won re-election and was in no danger of ever losing his seat, and is now stepping down not even a year into his term to do something that had likely been in the works since before he won re-election, likely because he didn't like being a lame duck member of congress. Couldn't be bothered to finish the term he promised he would and he's not leaving because of some sort of medical issue, just greed. Actions like these are exactly what chips away at what little faith people still have in politicians and is a smack in the fact to his constituents.

I honestly expected better from someone like Cicillini. He really seemed to be the rare member of congress that actually cared.

Except in this case, Biden's DOJ did try to re-open the issue and immediately concluded the case wasn't worth pursuing, probably because the last time such a case went to court, the defendant (John Edwards) won.
