...the corrupt Deep State/Media Complex threatening our duly elected President and our republic itself.

Mueller Investigation: Politics, Not Law Enforcement or Counterintelligence
Good article, but chances are Sessions would deny the request to setup a special counsel for Iranian nukes, just as he’s so far refused to setup one to investigate anything else related to the previous administration despite many calls for it.
The hypocrisy is incredible, since there was little evidence of a crime before Mueller’s SC was setup. As Trump’s recent tweets are saying, this is obviously a double standard, if not outright corruption on full display.
