The man arrested in connection with an apparent attempt to assassinate Donald Trump is a former supporter who turned against the former president in part for foreign policy reasons and later traveled to Ukraine, where he made an ill-fated attempt to raise a volunteer force to fight the Russians.

The revelations about Ryan Wesley Routh emerged Monday, a day after a Secret Service agent rousted him from a hiding place at the West Palm Beach, Florida, golf course where Trump had been playing. Sheriff’s deputies later took him into custody.

Routh, it was revealed in court papers, had been camped out in a wooded area with a loaded SKS-style rifle near the course for 12 hours before he was spotted, raising new questions about whether the Secret Service was doing enough to protect a politician who had already survived one assassination attempt.

Trump was on the fifth fairway and not in Routh’s line of sight when the agent “engaged” the suspect, said Ronald Rowe, acting director of the Secret Service. Routh also never fired his weapon.

But Routh, 58, was equipped to kill, the criminal complaint said. 

In addition to a digital camera and two bags, investigators found a loaded SKS-style 7.62x39 caliber rifle with a scope that had an “obliterated” serial number and a black plastic bag containing food likely to sustain Routh while he waited in the wooded area.

Routh was arraigned Monday at the Paul G. Rogers Federal Court House in West Palm Beach on charges of possession of a firearm by a convicted felon and possession of a firearm with an obliterated serial number.

The FBI has confirmed it is investigating “an apparent attempted assassination” of Trump on Sunday, but so far Routh has not been charged with trying to kill him.

Body camera video released by the Martin County Sheriff’s Office shows Routh wearing sunglasses and a pink T-shirt pulled over his head, exposing his midsection. He had been told to pull his shirt up to show he had no concealed weapons, Martin County Sheriff William Snyder told NBC News. He was arrested without incident.

The next day, Routh appeared unruffled, dressed in prison scrubs during his brief court appearance. He said he has a 25-year-old son, and he told the judge he has no money but owns two trucks in Hawaii, where he now lives, that are worth about $1,000 each.

Represented by a public defender, Routh was given a Sept. 23 return court date and was then sent back to jail.

There was no discussion of a possible motive. In a self-published book, Routh said he voted for Trump in 2016 and came to regret it after Trump made what he called a “tremendous blunder” in 2018 and withdrew the U.S. from the Iran nuclear deal.
