The family of slain conservative activist Charlie Kirk is asking a Utah court to require that all evidence admitted during the preliminary hearing for the man accused of killing him be visible to everyone lawfully present in the courtroom, arguing that public access is necessary to ensure transparency in the judicial process, according to The New York Times.

In a motion made public Thursday, an attorney representing Kirk's parents and his widow, Erika Kirk, argued that exhibits introduced by prosecutors, including video evidence, should be displayed in open court rather than shielded from those attending the proceedings.

"The Victim's Family's position is simple. At a minimum, every exhibit entered into evidence during the preliminary hearing must be visible to every person lawfully present in the courtroom," the filing states.

The motion argues that limiting public viewing of admitted evidence undermines confidence in the judicial system.

"To receive evidence in a manner shielded from those seated in the courtroom – as happened today – is not transparency," the filing says.

"And in the absence of transparency, speculation and conspiracy theories related to the tragic assassination of Mr. Kirk will continue to proliferate in the public domain, breeding doubt and distrust in the judicial system. This is not what anyone should want."

A representative for the Kirk family told Fox News that the request includes a 4K video of Kirk's shooting that prosecutors introduced as evidence in the preliminary hearing.

According to the representative, the family is not seeking to have the evidence released publicly or distributed to the media.

Instead, the request asks that anyone lawfully attending the hearing be allowed to view exhibits as they are presented in court.

The filing argues that members of the victim's family were present for the hearing but were unable to fully observe the proceedings because they could not see key evidence.

"The right 'to be present' is hollow if the victim or his representative is physically in the room but is prevented from seeing the evidence the Court is receiving," the motion states.

"A right to attend that does not include the ability to perceive what is happening is not meaningful presence at all," it continues.

The filing asks the court to ensure that evidence admitted for the remainder of the preliminary hearing is displayed in a manner visible to all courtroom attendees.

Tyler Robinson is charged with aggravated murder and other offenses in connection with Kirk's killing. The preliminary hearing is continuing as the court determines whether prosecutors have presented sufficient evidence for the case to proceed to trial.
