A "vocally anti-Trump" FBI agent is leading the investigation into the recent attempted assassination of Donald Trump in Florida.

The bombshell disclosure, shared by a whistleblower, vindicates longstanding suspicions that Trump and his supporters have harbored toward federal law enforcement.

The FBI agent in question, Jeffrey Veltri, is the special agent in charge of the Miami field office. Concerns about Veltri surfaced last year when a whistleblower alleged that he made anti-Trump social media posts.

Whistleblower exposes FBI agent

The whistleblower told Congress that the FBI's top brass, including director Christopher Wray, told Veltri to delete the posts. The whistleblower's complaint was first reported by the Washington Times in November.

The insider said Veltri's "vocally anti-Trump" views were known within the bureau, and that top officials were less concerned with his bias than keeping it private. The FBI dismissed the report at the time as "demonstrably false," and the agency has pledged "full confidence" in Veltri.

The suspect in last weekend's assassination attempt, Ryan Routh, camped out on the perimeter of Trump's golf course, coming within 300 to 500 yards of Trump before Secret Service spotted the rifle of his gun.

Veltri assured the public at a press conference the next day that the FBI would leave no stone unturned.

"We view this as extremely serious and are determined to provide answers as to what led up to the events that took place," Veltri said.

"I want to emphasize we are just a little over 24 hours into this investigation, so we are going to provide as much as we can publicly while our investigation is ongoing," he added. "We must also stress the U.S. attorney’s office is pursuing charges, and that limits some details we can publicly disclose."

Bias concerns in Trump probe

The FBI is handling the probe into a previous assassination attempt that left Trump bloodied in Butler, Pennsylvania. The agency has left major questions unanswered about the July shooting, particularly the motive of the gunman who was killed at the scene.

Within days of the shooting, FBI director Wray publicly speculated in front of Congress that Trump was not hit with a bullet. The bizarre claim led to backlash, and the FBI conceded that Trump was in fact shot.

The gunman behind the latest attempt, Ryan Routh, came onto the FBI's radar in 2019 for owning a firearm illegally. Routh is a convicted felon.

Routh shared anti-Trump sentiments on social media, and his truck has a Biden-Harris bumper sticker. He was also a passionate supporter of Ukraine.

In response to concerns about FBI politicization, Florida's Republican governor Ron DeSantis has launched an independent investigation into Routh's murder attempt.
