The man charged with trying to assassinate Donald Trump while he played golf last year in South Florida stood before a group of potential jurors in a Florida courtroom on Monday and said he was “sorry for bringing you all in here.”

Ryan Routh, wearing a gray sports coat, red tie with white stripes and khaki slacks, is representing himself in the trial that began with jury selection on Monday in the federal courthouse in Fort Pierce, Florida.

“Thank you for being here,” Routh told the first group of 60 jurors who were brought into the courtroom after U.S. District Judge Aileen Cannon introduced prosecutors and Routh to the panel.

Cannon signed off on Routh’s request to represent himself but said court-appointed attorneys needed to remain as standby counsel.

During a hearing earlier to go over questions that would be asked of jurors, Routh was partially shackled. But he did not appear to be restrained when the first of three batches of 60 potential jurors were brought into the courtroom on Monday afternoon.

Cannon dismissed the questions Routh wanted to ask jurors as irrelevant earlier Monday. They included asking jurors about their views on Gaza, the talk of the U.S. acquiring Greenland and what they would do if they were driving and saw a turtle in the road.

The panel of 120 potential jurors filled out questionnaires on Monday morning and the first group was brought into the courtroom during the afternoon session. The judge inquired about any hardships that would prevent them from sitting as jurors during a weeks-long trial. Twenty-seven noted hardships and the judge dismissed 20 of them on Monday.

The other two groups of jurors will return to the courtroom on Tuesday morning for similar questioning. Those who are not dismissed will then return at 2 p.m. Tuesday for further questioning about the case and their views.

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

Jury selection was expected to take three days in an effort to find 12 jurors and four alternates. Opening statements were scheduled to begin Thursday, and prosecutors will begin their case immediately after that.

Cannon told Routh last week 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.

Cannon is a Trump-appointed judge who drew scrutiny for her handling of a criminal case accusing Trump of illegally storing classified documents at his Mar-a-Lago estate in Palm Beach. The case became mired in delays as motions piled up over months, and was ultimately dismissed by Cannon last year after she concluded that the special counsel tapped by the Justice Department to investigate Trump was illegally appointed.

Routh’s trial begins 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.
