If you were paying attention, you would know the investigations are in process now
I pay attention and I know until Boehner authorizes committee chairs real power to compel testimony, nothing will happen.
Has Lois Lerner been called to account yet? Didn't think so.
After Articles of Impeachment are issued by the House, the Senate becomes a Jury even taking a different Oath, and the Chief Justice becomes the Senate President.
I watched as Trent Lott made a travesty of the process. A Chief Justice who apparently had no clue of his roll, frequently yielded his rightful power to the parliamentarian.
Senators solemnly took the new Oath and promptly set about breaking that Oath at every opportunity.
