Fox News reported on the initial findings from a House Task Force that highlighted alarming failures within the Secret Service.

“Although the findings in this report are preliminary, the information obtained during the first phase of the Task Force’s investigation clearly shows a lack of planning and coordination between the Secret Service and its law enforcement partners before the rally,” the report said.

“Put simply, the evidence obtained by the Task Force to date shows the tragic and shocking events of July 13 were preventable and should not have happened,” the report added.

Task Force Chair Mike Kelly (R-PA) has discreetly issued three subpoenas to local Pennsylvania agencies for “sensitive documents,” according to Politico. These documents are expected to be reviewed and included in a final report set for release this December.

Local authorities have previously disputed claims made by former Secret Service leadership regarding the adequacy of training and preparation, including accountability for securing the rally’s perimeter from which the gunman fired.

The investigation also uncovered that the Secret Service borrowed members of Trump’s detail from other federal agencies, with some receiving only brief webinar training before being deployed in the field.

Shortly before 20-year-old gunman Thomas Matthew Crooks began firing at Trump, grazing his right ear, a breakdown in communication between the Secret Service and other agencies caused “critical pieces of information … [to move] slowly due to fragmented lines of communication and unclear chains of command on July 13,” and the Secret Service “did not effectively verify responsibilities were understood and being executed,” the report says.

Also, there was no joint meeting between the Secret Service and its state and federal partnering agencies that day.

The communication breakdown also hindered agents’ ability to share crucial information about the shooter, according to the report. One example of the poor communication involved the initial identification of a suspicious individual, which was not communicated to the agency’s command post until 5:51 p.m.—almost an hour after it was first reported.

Three local officers had first observed Crooks’s unusual behavior, including the use of a rangefinder, around 5 p.m. that day.

“These observations were made independently, and based upon each officer’s experience, Crooks’s behavior and manner were suspicious,” the House report said.

An officer from the Butler Township Police Department, identified as witness four in the report, testified that he was one of the first to notice a long gun in Crooks’s possession. Unfortunately, that critical information did not reach the USSS counter-snipers who were engaged at the scene.

Crooks was able to fire more than eight rounds before he was shot and killed.

“From there, I just start yelling out to the guys that are there, I yell on the radio right away. I start saying, you know, ‘South end, He’s got a long gun, male on the roof.’ I just kept repeating, ‘He’s got a gun, he’s got a long gun,’” the witness told the task force, according to the report.

Politico noted that the report also stated: “To date, the Task Force has not received any evidence to suggest that message reached the former President’s USSS detail prior to shots fired.”
