1000%...because Sessions recused himself from any Russia investigation doesn’t mean he’s recused himself from investigating any crimes (such as leaks coming from Mueller’s office) or investigating potential conflicts of interest from Mueller or Rosenstien...
There is no Russia investigation. If there was, then Hillary would have been the target.
Trump needs to fire Sessions, Rosenstein and Mueller all on the same day.
Then have his new acting AG appoint a special counsel to investigate them.
Then dare Congress to impeach him.
