Prosecutors in the Manhattan District Attorney's Office have asked a judge to address what they describe as false claims made by the defense team for Luigi Mangione, who is accused of murdering UnitedHealthcare CEO Brian Thompson. The prosecutors' filing on Monday seeks to correct allegations that the District Attorney's Office was involved in developing the media access plan for Mangione's upcoming murder trial and in selecting which journalists would cover the proceedings.

In a letter to Judge Gregory Carro, Senior Trial Counsel Joel J. Seidemann stated that the defense's accusations are baseless and appear to be an attempt to spread misinformation and delegitimize the trial. Prosecutors denied having any role in the New York State Office of Court Administration's media access plan or in choosing reporters. Seidemann also urged Mangione's attorneys to remember their ethical obligations not to knowingly make false statements.

These claims and counterclaims emerged after Mangione's defense attorneys filed objections on Friday. The defense team, consisting of Karen Friedman Agnifilo, Marc Agnifilo, and Jacob Kaplan, argued that the court's planned restrictions on public and media access violate Mangione's constitutional rights to a public trial under the First, Sixth, and Fourteenth Amendments. They specifically objected to the absence of an overflow courtroom, limitations on coverage of jury selection, and what they characterized as a process that would allow only a select group of reporters access to the trial.

The defense attorneys also claimed they were informed that only 68 journalists would receive general access and that this selection process was allegedly outsourced to a private attorney representing several legacy media organizations. They requested the court hold a public hearing to identify the selected journalists, explain their selection process, and detail efforts to secure an overflow courtroom. Additionally, they asked the court to either broadcast the proceedings live or provide justification for not doing so.

Luigi Mangione faces murder and terrorism-related charges for the fatal shooting of Brian Thompson on December 4, 2024, outside a Manhattan hotel. He has pleaded not guilty. Mangione is charged in New York state court.
