A devastating report by the State Department’s inspector general Wednesday shows just why Americans are right to distrust Hillary Clinton.

The 78-page document (by an Obama appointee, no less) concludes that Clinton’s server and email practices as secretary of state violated department policy — and she and her team lied about it repeatedly.

It says she and her inner circle defiantly stonewalled the investigation, despite Hillary’s repeated assurances that she’d “talk to anybody, anytime.” It also says:

Clinton never sought an OK from State’s legal staff to use a private server, as required, and as her aides claimed. If she had, permission would’ve been denied.

Instead, her IT aides were warned “never to speak of the Secretary’s personal email system” — and neither her server nor her Blackberry “met [even] minimum security requirements.”

Instead, her IT aides were warned “never to speak of the Secretary’s personal email system” — and neither her server nor her Blackberry “met [even] minimum security requirements.” Despite her repeated denials, there were at least two attempts to hack into her system. Neither was ever reported to State’s security personnel, as required.

Clinton claimed she used a private system strictly for convenience. But when urged to also use an official email address, she refused, citing the risk that personal emails might become publicly accessible.

Tellingly, Clinton and top aides Huma Abedin, Jake Sullivan and Cheryl Mills refused to be interviewed by the IG.

Here’s the bottom line: Virtually everything Clinton has said about her emails has been a lie. And no longer can supporters laugh off Emailgate so easily.

Hillary’s culpability and her flouting of the law now seem clear. But that leaves one more shoe to drop: Will Attorney General Loretta Lynch indict the Democrats’ presumptive presidential nominee? If she doesn’t, she’ll need a good excuse why.
