Days before prosecutors are expected to publicly lay out their evidence in the assassination of Charlie Kirk, the defense lost another courtroom fight Thursday, failing to block cameras from next week's closely watched preliminary hearing.
In a brief order, the Utah Supreme Court declined to hear accused assassin Tyler Robinson's appeal of Fourth District Judge Tony Graf Jr.'s decision allowing cameras inside the courtroom.
The justices also deemed Robinson's request to delay the proceedings moot, clearing the way for next week's preliminary hearing to move forward as scheduled.
"The petition for permission to appeal from an interlocutory order is denied. The motion to stay is deemed moot," the order states.

CHARLIE KIRK JUDGE DENIES TYLER ROBINSON'S ATTEMPT TO HAVE POTENTIAL DEATH PENALTY REMOVED
Prosecutors allege Robinson fatally shot Kirk before fleeing the scene. He has been charged with aggravated murder, and prosecutors are seeking the death penalty. Robinson has not entered a plea.
The latest ruling comes less than a week after Judge Graf denied Robinson's request to strike the death penalty as a possible punishment.

Although Graf found a Utah County prosecutor in civil contempt over comments he made to the media, the judge ruled removing the death penalty would be "grossly disproportionate" and instead expanded jury selection safeguards to protect Robinson's right to a fair trial.

The Utah Supreme Court has not yet ruled on two additional defense petitions challenging Graf's pretrial orders.
One seeks to block prosecutors from relying on certain hearsay evidence during the preliminary hearing, while the other challenges Graf's decision not to require key witness Lance Twiggs to testify in person. Those appeals remain pending.
