Local cops arrested an armed man outside Donald Trump’s Coachella Valley rally on Saturday, and the local sheriff said it may have been a third assassination attempt against the former president.

The suspect — identified as 49-year-old Las Vegas resident Vem Miller — was caught at a checkpoint about a quarter-mile from the rally with fake VIP passes to the rally and fake press passes — as well as unregistered weapons, including a loaded shotgun, a handgun and a high-capacity magazine, according to the Riverside County sheriff’s office.

Miller did not have a valid ID when he was stopped at the rally checkpoint, and was detained after police searched his vehicle and found the weapons, law enforcement sources told The Post.

“We probably stopped another assassination attempt,” Riverside County Sheriff Chad Bianco said, according to the Riverside Press-Enterprise.

However, law enforcement sources told The Post that the FBI does not believe this was an assassination attempt, and the former president’s life was never in danger.

Miller — a registered Republican believed to have far right leanings — was booked for possessing a loaded firearm and a high-capacity magazine was released after posting $5,000 bail, police records show

He has an extensive history of petty run-ins with the law, sources said, and appeared to be a member of the sovereign citizens movement – a far-right movement built on conspiracy theories that believe governments have no authority over them.

The FBI calls the group “anti-government extremists,” who maintain that while they “physically reside in this country,” they remain “separate or ‘sovereign’ from the United States.”

In addition to trying to flout taxes and the court system, the FBI noted sovereign citizens are particularly opposed to traffic stops – to the point that one 25-year-old armed member was gunned down in 2023 after refusing to comply during a Utah traffic stop.

Miller has a master’s degree from UCLA, and in 2022 ran for Nevada State assembly, the newspaper reported.

He also appears to own a California-based CBD company, and has espoused conspiracy theories and virulently misogynistic rhetoric online.

The assassination-attempt reports follow a tense summer where two gunmen were caught in the nick of time during attempts to kill the former president.

In July, 20-year-old gunman Thomas Matthew Crooks opened fire on the former president during a rally in Butler, Pennsylvania.

Trump was struck in the ear by a bullet that came within millimeters of ending his life — while one bystander was killed and two more rally goers were wounded. Crooks was gunned down by Secret Service snipers moments after he fired his weapon.

Then barely more than two months later, a would-be gunman was caught with an assault rifle hiding in the bushes of Trump’s West Palm Beach golf club – while the former president was just 300 yards away golfing on the next hole.

The suspect, Ryan Routh, was spotted at the last moment when a Secret Service agent patrolling the president’s next hole spotted the barrel of his weapon sticking out of the bushes. Agents fired, but the gunman escaped and Routh was later apprehended fleeing on the highway.

He is believed to have holed up in the bushes undetected for around 12-hours waiting for his chance to kill Trump, according to federal prosecutors.
