2/ "Each panel will have 23 grand jurors, plus three alternates. One panel will meet Mondays and Tuesdays, the other Thursdays and Fridays. Both will work in secret and are expected to decide whether to hand up indictments in hundreds of cases. It is unclear which one will consider the much-anticipated election-meddling case.

When a grand jury meets, at least 16 members must be present to conduct business. At least 12 grand jurors must vote to bring an indictment."
