PROVO, Utah (AP) — Utah prosecutors were in court Monday seeking to convince a state judge they have enough evidence to bring to trial the man accused in Charlie Kirk’s assassination and seek the death penalty.Kirk’s parents and widow, Erika Kirk, were in the courtroom for the first time, along with Donald Trump Jr., President Donald Trump’s son. But Kirk’s family walked out of the courtroom after the prosecution’s first witness — a police officer — started testifying about Kirk’s arrival on campus the day he was shot.The five-day preliminary hearing will mark the most significant presentation of evidence in the case against defendant Tyler Robinson. Robinson’s parents also were present, a few rows behind where the Kirks sat as the hearing began. The 23-year-old defendant is charged with aggravated murder in the Sept. 10 assassination of Kirk, a conservative activist and ally of President Donald Trump, at Utah Valley University. Robinson turned himself in the day after the shooting.
