WATCH: Senate committee holds hearing on political violence in wake of Charlie Kirk’s killing

SALT LAKE CITY (AP) — The 22-year-old man accused of killing Utah’s Charlie Kirk can appear in court wearing street clothes but must be physically restrained because of security concerns, a judge ruled Monday.

A Senate subcommittee held a hearing on political violence in… Tuesday. Watch in the player above.

Tyler Robinson’s attorneys said photos of him in shackles and prison clothing would be widely circulated in a case that received widespread press coverage and public attention, which they said could prejudice future jurors.

Judge Tony Graf agreed to make some concessions to protect Robinson’s presumption of innocence before trial, agreeing that the case had attracted “extraordinary” public and media attention.

“Mr. Robinson should dress like a person who is presumed innocent,” Graf said during a virtual court hearing.

Utah prosecutors have charged Robinson with aggravated murder in the September 10 shooting of the conservative activist on the University of Utah campus. They plan to seek the death penalty.

Although Robinson has no prior criminal history, Graf said the charges he faces are very serious and raise safety concerns in the courtroom. Graf said before denying Robinson’s request to appear without restrictions that the court’s top priority was to protect attorneys, court staff and Robinson himself during what can be emotional hearings. However, members of the media were prohibited from photographing or photographing Robinson’s restraints.

Robinson is accused of shooting Kirk — an ally of President Donald Trump who has worked to steer young voters toward conservatism — from a rooftop overlooking a crowded courtyard at Utah Valley University in Orem.

Robinson was arrested the next night when he and his parents showed up to turn himself in to the sheriff’s office in his hometown in southwestern Utah, more than a three-hour drive from Orem.

While law enforcement agencies were combing the state for the shooter, Washington County Sheriff Nate Broxby said he received a phone call from a retired deputy telling him he knew who killed Kirk. The Robinson family reached out to the retired deputy, whom they knew through their involvement in The Church of Jesus Christ of Latter-day Saints, and worked with him to help negotiate a peaceful surrender.

“Part of the negotiations to get him to present himself was that we were going to handle it as sensitively and softly as possible to make him feel comfortable where he was going to show up in my office,” Brooksby said immediately after the arrest.

Prosecutors have since uncovered incriminating text messages and DNA evidence that they say links Robinson to the killing.

Robinson reportedly texted his romantic partner that he targeted Kirk because he “had enough of his hate.”

Graf ordered Robinson to appear on January 16 and 30 for his first public hearings. On Monday, he appeared from prison on a blacked-out screen and spoke only to confirm his presence.
