That’s not what the person you are linked to is saying. They are just claiming that the DOJ has a habit of not releasing their case files.
There’s no reason to assert that this habit just exist because of arguments about biasing the Jury, a stronger reason for that general habit is likely that releasing case files can sometimes bring evidence to light that was ignored at the trial and that makes the convicted person look innocent which isn’t what the DOJ wants. Prosecutors don’t want the defense to have access to all the evidence that can used to argue innocence.
Apart from that you wouldn’t need to open the full case file to selectively leak embarrassing information from it about Trump and/or start a case against Trump and put the victims accusing Trump on the stand.
