This may be more about optics and public education/awakening the masses to their criminal activity as opposed to actually writing indictments. Graham has framed the Senate area of inquiry, named the witnesses to be called. He has designed his own dog and pony show to expose these bad actors. They will either tell some truth, tell lies, declare the 5th or no show and be held in contempt. The people will see it all and make their own judgement. Grind the Dems noses right into the FISA turds and the world gets to watch their response.
