Sen. Ron Johnson has accused the Secret Service and FBI of covering up the truth about the Trump assassination attempt in Pennsylvania, declaring that ballistics evidence suggests there were “multiple shooters” engaged in a coordinated attack on the former president.

Appearing on Fox News’ Sunday Morning Futures with Maria Bartiromo, the Republican senator said, “Was it one rifle? Was it more than one? I’ve seen some pretty interesting video on the internet by experts that does certainly call into question what the FBI is telling us about a single shooter.”

The senator announced he has launched an investigation into the assassination and subsequent cover up and urged all eyewitnesses that have any information to “preserve” and “memorialize” what they saw, as that information could help the investigation.

Johnson emphasized the bipartisanship nature of the investigation into what occurred, saying: “Chairman [Richard] Blumenthal and I are dedicated to taking transcribed interviews with law enforcement and public — just members of the general public that were at that that rally.”

“If you took video, save it. Make a backup copy. We can glean things in terms of audio and in terms of where the shots came from.” Watch:

Sen. Johnson also appealed to members of the public who were at the rally to come forward with any information they have about the experience.

“We are only just beginning this but it’s so important that people who saw things, that have information, they preserve it, they memorialize what they saw, because memories change over time, they can be influenced,” said Sen. Johnson.

“Members of the general public who were at that rally, no matter how insignificant your piece of information might be, it might lend to provide the full story of what happened, because the American public need to understand what happened here.”

Secret Service and the FBI are obstructing Sen. Johnson’s bipartisan investigation.

“That sniper team that was in the AGR building, they were the first ones that went up on the roof, they were the first to encounter the dead assassin at that time, later on other people joined them and … told them to send the pictures they had taken to an ATF agent. Which I think is very strange.”

“We called up that ATF agent, that individual, and he said he is with the ATF – and now he’s gone dark.”

“We have also reached out to Secret Service agents on the ground and all we are getting is the run around.”

“We are getting information from local law enforcement and we appreciate that. But unfortunately federal agents are saying ‘Well go through your congressional liaison.’ Again, that’s going to be unacceptable.”

“I wish I could rely and have faith in the FBI and Secret Service to do a truthful accounting of this but that has not been my experience with the Russian Collusion Hoax and for years dealing with federal law enforcement. We need completely separate and independent investigations and it needs to start now.”

Sen. Johnson was referring to audio forensics information which went viral on X this week following the shooting.

The audio forensics report also confirms there were likely three weapons fired at the Trump rally. The first three shots were consistent with alleged weapon A, the next five were consistent with alleged weapon B, and the final “acoustic impulse” was emitted by a possible weapon C.

All of the evidence points to the event being an inside job by government and security agencies rather than the work of a 20-year-old lone wolf who was rejected from his high school rifle club because he couldn’t hit a target from a distance of 50 yards.

A bombshell admission by the Secret Service spokesman Monday revealed Trump’s permanent detail were stood down for the Butler, Pennsylvania rally on Saturday and replaced with temporary agents.
