None of us know how many indictments are being wrapped up.
The findings of Grand Juries are kept secret until the Grand Jury is ready to release the indictments to media and others.
Grand jury proceedings are much more relaxed than normal court room proceedings. There is no judge present and frequently there are no lawyers except for the prosecutor. The prosecutor will explain the law to the jury and work with them to gather evidence and hear testimony. Under normal courtroom rules of evidence, exhibits and other testimony must adhere to strict rules before admission. However, a grand jury has broad power to see and hear almost anything they would like.
However, unlike the vast majority of trials, grand jury proceedings are kept in strict confidence. This serves two purposes:
1. It encourages witnesses to speak freely and without fear of retaliation.
2. It protects the potential defendant's reputation in case the jury does not decide to indict.

The people throwing hand grenades at Sessions and his people, have zero knowledge of what is being done.
Sorry but after a Grand Jury is finished or if it is doing long term work it can issue an indictment and not open it until the DOJ is ready.
There is a running list, gOOgle it.
