Probably not. In Illinois where I am, at least, judicial matters are excluded from the Freedom of Information Act. You do have a free speech right to some judicial documents under the 1st Amendment to the federal constitution and possibly under a State constitution. The transcripts of the actual grand jury session are "secret" but generally available to the defendant's attorney, but not the public. Information on when a grand jury went home might not be restricted though, and might be available, if it was recorded somewhere.
