Trump is probably on the list, so he has to protect that. The Democrats had it during their entire presidency; even if they didn’t want turmoil during their time in office, they could have released it after their presidential defeat and before Trump took office.
The point I’m making is Biden never campaigned on releasing the Epstein files. So it shouldn’t be surprising that he protected the people on the list. Trump did and his idiots fully expected him to release the list because he’s an honest person who keeps his promises. Trump knowingly and intentionally got votes from the psycho qanon types who have always believed trump is playing 4D chess.
It’s important to note that the goal posts have moved. Originally people wanted to see the “black book” which may be what the client list has come from. The black book got released and it’s got lots of people in it but it didn’t prove any crimes, only that he associated with them. People kept talking about it and believed it was being kept secret because nothing happens and no one got charged with anything. I believe the “client list” which appears to be a new idea, is directly talking about a list of people who the fbi have information on of committing crimes where Epstein supplied underaged girls to them.
