FORT PIERCE, Fla. — Jury selection is set to begin Monday in the trial of a man charged with trying to assassinate Donald Trump while he played golf last year in South Florida.

The court has blocked off four weeks for the trial of Ryan Routh, but attorneys are expecting they’ll need less time.

Jury selection is expected to take three days, with attorneys questioning three sets of 60 prospective jurors. They’re trying to find 12 jurors and four alternates. Opening statements are scheduled to begin Thursday, and prosecutors will begin their case immediately after that.

U.S. District Judge Aileen Cannon signed off in July on Routh’s request to represent himself but said court-appointed attorneys need to remain as standby counsel. Cannon confirmed during a hearing last week that Routh would be dressed in professional business attire for the trial. She also explained to Routh that he would be allowed to use a podium while speaking to the jury or questioning witnesses, but he would not have free rein of the courtroom.

The trial will begin nearly a year after prosecutors say a U.S. Secret Service agent thwarted Routh’s attempt to shoot the Republican presidential nominee. Routh, 59, has pleaded not guilty to charges of attempting to assassinate a major presidential candidate, assaulting a federal officer and several firearm violations.

Just nine weeks earlier, Trump had survived another attempt on his life while campaigning in Pennsylvania. That gunman had fired eight shots, with one bullet grazing Trump’s ear, before being shot by a Secret Service counter sniper.

Prosecutors have said Routh methodically plotted to kill Trump for weeks before aiming a rifle through the shrubbery as Trump played golf on Sept. 15, 2024, at his West Palm Beach country club. A Secret Service agent spotted Routh before Trump came into view. Officials said Routh aimed his rifle at the agent, who opened fire, causing Routh to drop his weapon and flee without firing a shot.

Law enforcement obtained help from a witness who prosecutors said informed officers that he saw a person fleeing. The witness was then flown in a police helicopter to a nearby interstate where Routh was arrested, and the witnesses confirmed it was the person he had seen, prosecutors have said.

The judge last week unsealed the prosecutor’s 33-page list of exhibits that could be introduced as evidence at the trial. It says prosecutors have photos of Routh holding the same model of semi-automatic rifle found at Trump’s club.

Routh was a North Carolina construction worker who in recent years had moved to Hawaii. A self-styled mercenary leader, Routh spoke out to anyone who would listen about his dangerous, sometimes violent plans to insert himself into conflicts around the world, witnesses have told The Associated Press.

In the early days of the war in Ukraine, Routh tried to recruit soldiers from Afghanistan, Moldova and Taiwan to fight the Russians. In his native Greensboro, North Carolina, he was arrested in 2002 for eluding a traffic stop and barricading himself from officers with a fully automatic machine gun and a “weapon of mass destruction,” which turned out to be an explosive with a 10-inch fuse.

In 2010, police searched a warehouse Routh owned and found more than 100 stolen items, from power tools and building supplies to kayaks and spa tubs. In both felony cases, judges gave Routh either probation or a suspended sentence.

In addition to the federal charges, Routh also has pleaded not guilty to state charges of terrorism and attempted murder.
