You being a lawyer and all… How much of this evidence can the justice department just release? What is it you know exists that you want to see?
Of the entire file?
There would have to be a privilege of some kind, or a statutory exemption of which I'm not aware. The most common privilege claim for this would be that there is an ongoing criminal investigation, but if that were the case they'd have had to say so in response to any formal inquiries. And even that privilege is not absolute.
The only thing I've heard even remotely coming close to a claim of privilege is the worry that people could be named who are not actually guilty of anything. But that is not a legal objection, its a judgment of no legal meaning. And that is particularly so when, if it were just a person who got a ride on an airplane, but there is no report of misconduct, they can dismiss on that grounds.
Point is, if there were a legitimate, real, legal objection or privilege it would have been invoked.
And as above my worry is that Trump and Bondi are now going to claim that the denial of the motion to release the grand jury testimony equates to that, and it simply does not.
If you are asking just about the grand jury proceedings, there is a federal rule of criminal procedure, 6 which is quite involved, but the part that would apply here, seems to me to be this:
(E) The court may authorize disclosure—at a time, in a manner, and subject to any other conditions that it directs—of a grand-jury matter:
(i) preliminarily to or in connection with a judicial proceeding;
(ii) at the request of a defendant who shows that a ground may exist to dismiss the indictment because of a matter that occurred before the grand jury;
(iii) at the request of the government, when sought by a foreign court or prosecutor for use in an official criminal investigation;
(iv) at the request of the government if it shows that the matter may disclose a violation of State, Indian tribal, or foreign criminal law, as long as the disclosure is to an appropriate state, state-subdivision, Indian tribal, or foreign government official for the purpose of enforcing that law; or
(v) at the request of the government if it shows that the matter may disclose a violation of military criminal law under the Uniform Code of Military Justice, as long as the disclosure is to an appropriate military official for the purpose of enforcing that law.
The law surrounding when such a showing has been made is complex. State rules may be different and less complex. Depends on which grand jury we are talking about -- state or federal.
