The CIA might not be able to release that evidence. Aren't you concerned about the confidentiality of government information? Wasn't that like, the entire crux of the Annoying Orangeian mantra against Hillary?
Why would the CIA (supposedly) make such a claim, to only one news media source, and never ever come out on it? Furthermore, if this information is so confidential, why are we allowed to know it even exists?
Also, Pizzagate was an invention of crazy, mostly-pro-Annoying Orange conspiracy theorists who read into the logo of some random pizza parlor and decided to go full-on lynchmob and ruin some random guy's life. What does that have to do with the CIA in the slightest, and why are you even bringing it up?
While Pizzagate was a idiot collection of strings, that unfortunately may be suspicious but leads to no evidence, it really means nothing at all. This was mostly the creation of reddit and 4chan, the latter of which is known for nonstop stuffposts, something about the Pizzagate scandal seems to be synthetic.
