You'll see Trump supporters say 'is any of the information released been proven false?'

This is a red herring, it's not about the information, it's likely true, it's Wikileaks themselves who release information that fits their narrative, and then shapes it in a false manner.

For instance here is a recent Tweet:

The screenshot from the Tweet alludes to being said secret. However, you can find the exact same text online here:

Either I am an elite hacker, or Wikileaks is full of shit.
