The government paid attorneys work for the USA and in turn, they work for you and me. The sitting president would have stronger cause to decide if a document shared between them and the previous president was privileged. In the case of a situation were an attack on the capitol and espionage issues that risk the lives of assets and agents, the current president would have much more say than the impeached idiot that stole documents after going on and on about made up security issues with all of his opponents at every level. He can't claim ignorance of guilt since he placed that guilt on multiple innocent people and then escalated the punishment he wanted to happen.
Then there is the issue that the judge involved in the "Special Master" thing should at most have mentioned it to another judge and then got herself out of the loop since she has a connection and debt to the jerk she is suddenly showing up to help.
Third, and this is the big issue, WTF, she is trying to step into a law suit to slow it down, that in any other case would have started with the accused seeing a warrant. The moment a secret document was found, the next thing we would normally see, is the accused disappearing and needing all conversations, papers, and materials exchanged to be searched, witnessed and approved. This case is already slower than it would be for anyone else.
Anyone other than a high ranking Republican politician would have been subject to immediate incarceration.
I can understand her wanting to help TFG. I doubt TFG appointed a lot of people he didn't either have compromat on or was recommended by someone holding compromat on TFG.
