Former President Donald Trump wasn’t harmed in Sunday’s apparent assassination attempt as he golfed near his Florida club. But the second attack on his life in barely two months is likely to further unsettle an election cycle already marked by upheaval.

The man suspected in the incident, Ryan Wesley Routh, camped outside the golf course in West Palm Beach with food and a rifle for nearly 12 hours, according to court documents filed Monday. He is accused of lying in wait for the former president before a Secret Service agent opened fire, thwarting the potential attack.

Here are five things to know about what happened and where the investigation stands:

Routh, 58, faces charges of possessing a firearm despite a prior felony conviction and of possessing a firearm with an obliterated serial number. Additional charges are possible.

The suspect lived in North Carolina for most of his life before moving in 2018 to Kaaawa, Hawaii. He and his son operated a company building sheds, according to an archived version of the webpage for the business.

Routh appeared briefly in federal court in West Palm Beach on Monday. He had frequently posted on social media about the war in Ukraine and had a website where he sought to raise money and recruit volunteers to go to Kyiv to join the fight against the Russian invasion.

“Fight and die to stop aggression,” he posted on X in February 2023 about Ukraine. “Everyone should be outraged and helping.” In a video circulating online, Routh said, “This is about good versus evil.”

He also wrote separately on X, “I am going to fight and die for Ukraine,” and he even traveled there.

Video shot by The Associated Press showed Routh at a small demonstration in Kyiv’s Independence Square in April 2022, two months after Russian President Vladimir Putin ordered an invasion of the country. A placard he was holding said: “We cannot tolerate corruption and evil for another 50+ years. End Russia for our kids.” Routh wore a blue vest with the U.S. flag on the back.

That same day, Routh also visited a makeshift memorial to “Foreigners killed by Putin.”

But Routh never served in the Ukrainian army or worked with its military, said Oleksandr Shahuri of the Foreigners Coordination Department of the Ukrainian Ground Forces Command.

Routh’s politics, meanwhile, don’t appear consistently aligned to one party or the other.

In June 2020, he offered a post on X directed at then-President Trump to say he would win reelection if he issued an executive order for the Justice Department to prosecute police misconduct. That year, he also posted in support of the Democratic presidential campaign of then-U.S. Rep. Tulsi Gabbard of Hawaii, who has since left the party and endorsed Trump.

However, in recent years, his posts suggest he soured on Trump, and he expressed support for President Joe Biden and Vice President Kamala Harris.

In July, following the assassination attempt on Trump in Pennsylvania, Routh urged Biden and Harris to visit those wounded in the shooting at the hospital and to attend the funeral of a former fire chief killed at the rally.

Voter records show he registered as an unaffiliated voter in North Carolina in 2012, most recently voting in person during the state’s Democratic Party primary in March 2024. Federal campaign finance records show Routh made 19 small political donations totaling $140 since 2019 using his Hawaii address through a political action committee that supports Democratic candidates.

Records show that while living in Greensboro, North Carolina, Routh had multiple run-ins with law enforcement. The top FBI official in the Miami, Jeffrey B. Veltri, said Routh has numerous felony charges for stolen goods between 1997 and 2010. He also was the subject of a closed investigation in 2019 when someone reported he was in possession of a firearm despite his felony convictions, but Veltri said the tipster would not confirm making the report.

Routh was convicted in 2002 of possessing a weapon of mass destruction, according to online North Carolina Department of Adult Correction records.

How did this happen?

Authorities spotted a firearm poking out of shrubbery on the West Palm Beach golf course around 400 to 500 yards from where Trump was playing. As the former president was moving through the fifth hole’s fairway, an agent who was visually sweeping the area of the sixth hole’s green saw the subject, armed with what he perceived to be a rifle, and immediately discharged his firearm, said acting Director Ronald Rowe Jr. of the U.S. Secret Service.

Rowe said Routh “did not have a line of sight to the former president” and did not fire at Secret Service agents before fleeing.

Routh sped away before being captured in a neighboring county. Body camera footage of Routh’s arrest showed him walking backward with his hands over his head on the side of a road before being handcuffed and led away.

The suspect is believed to have been positioned at the tree line of the golf course from about 1:59 a.m. to 1:31 p.m. Sunday. A digital camera, a loaded SKS-style rifle with a scope, and a plastic bag containing food were recovered from the area.

Trump’s protective detail has been higher than some of his peers because of his high visibility and his campaign to seek the White House again. His security was bolstered days before the July 13 assassination attempt in Pennsylvania because of a threat on Trump’s life from Iran, U.S. officials said.
