Lawyers representing Tyler Robinson, charged with the murder of conservative figurehead Charlie Kirk, have disclosed the witnesses prosecutors plan to introduce and requested a postponement of the preliminary hearing.

In a recent filing by Robinson’s legal team, it was revealed that the prosecution aims to summon Robinson’s parents, along with his roommate and partner, Lance Twiggs, to testify at the upcoming preliminary hearing. The defense is also seeking a minimum six-month extension for the hearing, which is currently set for May 18.

Robinson’s attorneys highlighted that during a meeting on March 12, they received over 600,000 files from the prosecution, requiring substantial time for thorough examination. They also pointed out that the discovery process is still ongoing.

The defense team emphasized, “The discovery materials in this case are incomplete, extensive, and demand intricate processing.”

Additionally, a forensic biologist working with the defense indicated that a six-month period would be necessary to thoroughly analyze the evidence.

The filing by Robinson’s defense attorneys doesn’t request that the next court hearing on April 17 be pushed back. That hearing will be focused on public and media access to future court hearings, which includes a defense motion to ban all cameras from the courtroom.

Robinson’s defense team plans to show evidence they believe contains “harmful and prejudicial media coverage of this case thus far.”

“While there is simply not enough time to present all of what is referenced in the ‘motion to exclude cameras,’ the compilation anticipated will highlight the most egregious and most concerning media coverage impacting Mr. Robinson’s case,” his attorneys wrote.

During a Feb. 24 hearing, Judge Tony Graf denied a motion from Robinson’s lawyers that would have removed prosecutors from the case.

Robinson’s defense team tried arguing there was a conflict of interest because a prosecutor’s daughter was at the event at Utah Valley University when Kirk was shot and killed.

Graf, in his response, said the court was “unpersuaded” by the defense team’s argument of an “appearance of bias” from prosecutors.

“Because defendant has not established a factual basis for a finding of conflict of interest or an objective appearance of impropriety, rising to a constitutional concern, his motion is respectfully denied,” Graf said. “In sum, the defendant has not shown that there is a significant risk that Mr. Gray’s loyalty to his daughter has or will materially limit representation of the state. Nor has defendant demonstrated that his due process rights are compromised by the continued prosecution of this case by the Utah County Attorney’s Office.”

Robinson faces multiple charges after he allegedly killed Kirk on Sept. 10, 2025, which include aggravated murder. His charges are death penalty eligible.
