Lawyers for Tyler Robinson, the man accused of killing conservative activist Charlie Kirk, argued during a hearing on Friday that cameras should be barred from the courtroom for the upcoming murder trial, pointing to negative pretrial coverage of their client.

Robinson’s lawyers brought two witnesses to the stand to support their assertion that having cameras in the courtroom would violate his right to a fair trial. Most of the questioning came when Dr. Brian Edelman, a trial consultant brought as a witness for Robinson’s lawyers, was on the stand, with him testifying that cameras in the courtroom and media reports ahead of the trial have been prejudicial toward Robinson.
