Here is a link to Andrew Napolitano's article about The Inspector General's Report on Hillary Clinton.
The inspector general's report is damning to Clinton. It refutes every defense she has offered to the allegation that she mishandled state secrets. It revealed an email that hadn't been publicly made known showing Clinton's state of mind. And it paints a picture of a self-isolated secretary of state stubbornly refusing to comply with federal law for venal reasons; she simply did not want to be held accountable for her official behavior.
The report rejects Clinton's argument that her use of a private server "was allowed." The report makes clear that it was not allowed, nor did she seek permission to use it. She did not inform the FBI, which had tutored her on the lawful handling of state secrets, and she did not inform her own State Department IT folks.
The report also makes clear that had she sought permission to use her own server as the instrument through which all of her email traffic passed, such a request would have been flatly denied.
In addition, the report rejects her argument — already debunked by the director of the FBI — that the FBI is merely conducting a security review of the State Department's email storage and usage policies rather than a criminal investigation of her. The FBI does not conduct security reviews. The inspector general does. This report is the result of that review, and Clinton flunked it, as it reveals that she refused to comply with the same State Department storage and transparency regulations she was enforcing against others.
