For what purpose? Sessions did not assign Huber to prosecute anyone connected to the campaign.
“For what purpose? “
Good question. I know it exists, but don’t know the purpose.

“[Huber] has convened a grand jury For what purpose?”
The obvious answer would be to get search warrants, subpoenas and/or get criminal charges filed.
Those are the main functions of Grand Juries.
The process for the IG requires that any indications of criminal activity must be immediately brought to the Attorney General (AG) - they can not hold them for a final report, or while they investigate.
The AG is then accountable for proper handling of that referral - the normal default response is to have a prosecutor investigate the issue. If a prosecutor finds grounds, he can go to a Grand Jury to approve criminal charges, and prosecute. US Attorney’s already have that power.
That is the normal process, and it is normally done without revealing it to the press/public. Once charges are filed, it becomes public. Visible raids and arrests also make investigations public.
