To add to the litany of unbelievably bad security decisions made by the Secret Service, a whistleblower is now claiming that the agency rejected an offer by a police department to work together to secure the Pennsylvania rally where former President Donald Trump was shot against rogue drones.

As previously relayed by The Dallas Express, the 20-year-old would-be assassin reportedly flew a drone over the rally site in Butler County, probably to perform reconnaissance, just hours before Trump took the stage.

Here’s some of what Breitbart reported on the latest revelations:

Sen. Josh Hawley (R-MO) on Thursday revealed in a letter a whistleblower told him the U.S. Secret Service (USSS) turned down offers from a local law enforcement partner to utilize drone technology to secure the July 13 rally where a shooter attempted to assassinate former President Donald Trump.

Hawley wrote in a letter sent Thursday to Department of Homeland Security Secretary Alejandro Mayorkas, whose agency oversees the Secret Service:

According to one whistleblower, the night before the rally, U.S. Secret Service repeatedly denied offers from a local law enforcement partner to utilize drone technology to secure the rally. This means that the technology was both available to USSS and able to be deployed to secure the site. Secret Service said no. The whistleblower further alleges that after the shooting took place, USSS changed course and asked the local partner to deploy the drone technology to surveil the site in the aftermath of the attack.

The Secret Service has not explained why there was no drone surveillance for the rally — which could have helped the agency see the sniper climbing to the rooftop of a building and positioning himself with a rifle before firing at Trump.
