Has this Grand Jury been dismissed? Will they meet next week?
Yes. It's not at all unusual for a grand jury to take the weekend off... in fact it would be highly unusual for a grand jury (not to be confused with a trial jury) to work weekends.
The headline is misleading, as many TPNN articles are.
The GJ will meet again on Monday. The only news is that they failed to have a decision by this weekend, as some news sources suggested.
