Democratic presidential nominee Hillary Clinton was classified as an example of "careless or disgruntled employees" in an Army training presentation, according to sources confirmed by NBC News on Tuesday.
U.S. military officials confirmed that they were teaching a lesson on securing classified materials and improving safety:
A spokesperson from the Army's Training and Doctrine Command said the slide was developed 18 months ago.
"As is common with Army training requirements, the local unit was given latitude to develop their own training products to accomplish the overall training objective," the spokesperson said in a statement.
"This particular presentation had not been reviewed or approved by the unit's leadership, and does not reflect the position of the Army. The training presentation has since been removed."
A U.S. military official told NBC News that the slide — with a header reading "Who is the threat? Insiders" — was used at at Fort Leonard Wood in Missouri.
Clinton's slide was developed over a year before FBI Director James Comey made his decision not to recommend any charges for Clinton's private email server. However, Comey and the Army training slide both agreed that Clinton was "careless." Comey even went further by saying that Clinton was "extremely careless" in her handling of sensitive and highly classified information.
The Clinton campaign did not respond to requests for comment from NBC News.
In addition to Clinton, the Army training presentation included several other individuals who have leaked classified information or posed a threat in the workplace:
Next to Clinton on the slide is a photograph of former CIA Director and retired Army Gen. David Petraeus, who pleaded guilty in 2012 to a misdemeanor charge of mishandling classified materials by sharing them with his former mistress and biographer.
Above them are pictures of Army Maj. Nidal Hasan, who killed 13 people in a 2009 gun rampage at Fort Hood, Texas; Chelsea Manning, a soldier who is serving a 35-year sentence in a military prison for sharing a trove of classified documents with WikiLeaks; Edward Snowden, a former National Security Agency contractor who has been living in exile since leaking classified documents on government surveillance; and Aaron Alexis, who killed 21 people in a shooting at the Washington Navy Yard in 2013.
MSNBC correspondent Andrea Mitchell told fellow reporter Chris Jansing on Tuesday that it was pretty "astounding" that if Clinton were to win the election, she would be the U.S. commander-in-chief.
