I don't think 3 hours is enough to get votes on the rumored (by the Libs) 22 indictments. Barring an extension, Friday is the last day for the GJ. I doubt if Fitz had more charges to present that he would have let the GJ leave early today. Now the question is if there were votes this morning (or last week) or if Fitz was going through the key facts with the GJ to explain why certain charges were not being brought.
They were there for such a short time, I'm thinking they just issued subpoenas, or something like that.
