I'd like to see a subpoena issued for it, but I doubt that is going to happen. Congress does not have the authority to act as prosecutor--only the Executive Branch does. And I can't see President Pinocchio's Justice Dept. doing anything about it. I don't think it matters that much, because Mrs. Clinton is being damaged politically by this, without any criminal prosecution, and it may well get worse. The other leaders of the Democratic Party seem to be stuck with her, even though they evidently have quite a bit of doubt about her as their candidate.
