Tyler Robinson’s lawyers urged a Utah judge to close a July pretrial hearing to the public, alleging it could harm his ability to have a fair murder trial for allegedly killing conservative activist Charlie Kirk.

One of Robinson’s lawyers, Staci Visser, argued to Judge Tony Graf that the preliminary hearing, scheduled for July 6-10, should be held behind closed doors, expressing concern that evidence presented could be reported widely by the media and possibly taint the jury pool for the murder trial. Earlier this month, Graf denied a bid by Robinson’s lawyers to ban cameras from the courtroom during the trial.
