Is his signature there or not?
Sure, but as FBI Director he had nearly total freedom to do whatever he wanted with regard to investigations. I doubt they’ll ever be able to prove a case against him for all that he did. If this is one thing they can use to mess up his life, tarnish his so-called reputation and cost him some money, I’m all in favor. The rest - he’s likely going to get away with it all. And it won’t be the first time - think of all the illegal and shady stuff J Edgar Hoover did - for decades - and got away with all of it.
