If the files were released right now (if they exist) you wouldn't believe they were the original, untampered version. But the only way to essentially clear the air for Trump is to release something or get Maxwell to sing. But to get that, a pardon or mitigated sentence/re-trial would be needed - which would ultimately frame Maxwell as an anti-hero and Trump as a protector of villains.

And curiously, why does Maxwell think she'd be safe outside of prison?
