News just broke that the Secret Service may have tried to to assassinate President Obama for the third time—according to reports, agents allowed a guy with a gun to get in an elevator with the president earlier this month and had no idea he was armed until someone else pointed it out.

According to the Washington Post, the president was in Atlanta at the Centers for Disease Control and Prevention on Sept. 16 when the Secret Service broke protocol (once again), allowing an armed CDC security guard to board the elevator with them.

Agents became suspicious when the man started filming Obama during the elevator ride and ran a background check on him, revealing three prior assault and battery convictions.

The Washington Examiner reports the guard's supervisor declared his behavior to be "highly irresponsible"—and then demanded the guard turn over his gun.

Secret Service agents were reportedly "shocked" to learn he was armed.

Per the Examiner:

Before the president travels anywhere, Secret Service agents make it their job to know who will have access to the president and anyone with a gun needs special clearance and may not be allowed to carry it when the president is onsite.

In addition to the Secret Service, only sworn law enforcement officers are allowed to be armed at a location where the president is visiting, the source said. Contract security officers are not allowed to be armed.
