If Comey or Clinton did anything illegal, then the Trump DOJ should initiate legal proceedings.
You don't think a special investigator should crawl as far up their (and all of their associates) asses as they have with Trump???? Maybe LOOKING for a crime??? Is that how it's supposed to work???
If there is evidence of a crime at high levels, then a Special Prosecutor investigation is warranted. No one is above the law (not Hillary Clinton, James Comey, Don McGahn, Donald Trump Jr., etc.)
