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.
Because Democratic leadership is aware that Republicans aren’t their actual enemies, and a ton of them are also on the list.
The democrats are aware that their names are on the list and they’re the only ones that will be held accountable for it. The republicans will hold witch burnings while completely ignoring their own member’s names on the list.
