(NEW YORK) — Luigi Mangione asked a judge on Wednesday to postpone his federal trial from September 2026 to January 2027.

Mangione argued he could not properly prepare for his federal trial — which is set to begin with jury selection on Sept. 8 and opening statements on Oct. 13 — while he is on trial in the state case, which begins June 8.

The state trial would be ongoing while hundreds of potential jurors for the federal case begin filling out questionnaires on June 29.

“Mr. Mangione is now in the impossible position of having to review 800 jury questionnaires during the week of June 29, 2026, while on trial for second-degree murder in state court,” defense attorney Karen Friedman Agnifilo wrote in a letter to the judge. “As a practical matter, this would not be possible.”

She also argued potential jurors would be “bombarded” by news accounts of the state trial.

“As a result, forcing Mr. Mangione to start the state trial on June 8, 2026 — three weeks before potential federal jurors start filling out juror questionnaires a few blocks away in Mr. Mangione’s federal case — guarantees that the fairness and impartiality of Mr. Mangione’s federal jurors will be negatively impacted by weeks of media reporting,” the defense said.

Federal prosecutors are expected to oppose moving the trial date.

Mangione pleaded not guilty to state and federal charges after he was arrested for allegedly gunning down UnitedHealthcare CEO Brian Thompson in Midtown Manhattan in December 2024.

In January, U.S. District Judge Margaret Garnett took the death penalty off the table in the federal case.
