An Army soldier used a slide of Hillary Clinton in a power point presentation on handling classified information and under a heading about American “insiders” who pose a “threat” to national security.

The picture of Clinton, the Democratic presidential nominee, appears in a rogue's gallery of six people, including at-large NSA-snitch Edward Snowden and Nidal Hassan, the Army psychiatrist and radicalized Muslim who fatally shot 13 people in 2009 at Fort Hood, Texas, as reported first by The Washington Examiner. 

An Army spokesman on Tuesday confirmed to Fox News that the picture of the slide used in news accounts is authentic.

Maj. Thomas Campbell, the U.S. Army Training and Doctrine Command spokesman, also said the slide was part of a smaller-scale Army unit’s seminar on best practices for handling classified information and maintaining operational security.

However, its use was not “reviewed or approved by the unit's leadership, and does not reflect the position of the Army," Campbell said.

Clinton was the subject of a roughly two-year-long FBI investigation into her use of a private server for official correspondence while secretary of state from 2009 to 2103.

FBI Director James Comey said the agency found three emails that included parts of classified information and that Clinton was “extremely careless.” However, he did not recommend criminal charges and the case was close in July.

The U.S. Army W.T.F! Moments Facebook page on Sunday appeared to first post the slide of Clinton and the others, according to The Examiner.

The other three images on the slide are of retired CIA Director David Petraeus, who gave classified information to his biographer and mistress; Aaron Alexis, the Washington Navy Yard sniper; and Chelsea Manning, who gave classified information to WikiLeaks.
