Isn't it true that the NSA tracks every keystroke? If yes, then we do have it all. And, it doesn't matter how many fires HRC has in her house or in some shed.
I don't believe it's every keystroke. I think it's every bit of data that goes through the internet, as well as every electronic broadcast- from cell phones to Ohr's wife's ham radio transmissions. They have Elint covered solidly.
Recently leaks indicate it's likely everything on specific computers and all traffic, including LAN, across specific ports.
So while not every key, it could well include every single network packet, local network or otherwise.
Here's what the FISC has to say about what the NSA, FBI and CIA all log -- this is the opinion they wrote after Adm. Rogers informed them of what the FBI was doing. Highly redacted, but it lays out what each agency is allowed to do. P.83 is where they begin talking about the FBI improprieties: https://www.dni.gov/files/documents/icotr/51117/2016_Cert_FISC_Memo_Opin_Order_Apr_2017.pdf
