Seriously. Let's look at the evidence. The FBI's total reliance on the dodgy Crowdstrike report and its complete failure to examine the DNC servers to verify any of Crowdstrike's claims. The reliance on a clearly fake dossier cooked up at the request of a Dem linked opposed research company. The ever expanding investigation run by a close friend of one of the key witnesses (in a total and clear conflict of interest) branching out in every direction because the original Trump/Russia interference/collusion story is falling apart for lack of credible evidence.
How do you know what they are relying on? I wasn't aware you were an FBI agent and/or part of Mueller's team. You do realize there is a lot going on that we don't know about, right? Did you ever consider what the NSA might have scooped up? They may or may not have gotten anything but they have access to a lot of the world's communications and Snowden's leaks do show that they store a massive amount of data collected, which is perfect for this kind of investigation.
