The judge overseeing accused Ivy League assassin Luigi Mangione's federal case shrugged off his defense team's push to have the trial delayed, saying she doesn't want to be "held hostage" by the schedule of a state court judge handling another case against him.

U.S. Marshals escorted Mangione into the courtroom at 11:24 a.m. He wore a tan jail jumpsuit with his sleeves rolled up, leg shackles and no handcuffs.

The judge entered a minute later.

Karen Friedman Agnifilo, one of Mangione's lead defense lawyers, asked for several months of extra time, saying Mangione's legal team needed to prepare for the federal case after his state trial.

"I don't think what we're asking for is unreasonable," she said.

Assistant U.S. Attorney Dominic Gentile argued that the defense’s logistical concerns could be addressed by changing the jury questionnaire schedule, which was set for a capital case. Mangione no longer faces the potential death penalty.

He added that both cases are expected to rely on the same facts and witnesses.

Judge Margaret Garnett said she was more concerned about the jury selection process rather than trial prep — telling the parties she doesn't envision a particularly complex proceeding.

She said her role is to ensure Mangione gets a fair trial in her courtroom, and she said whatever happens in the state case is not her concern.

"I'm a little troubled," she said.

After a roughly 30-minute hearing, she proposed keeping close to the schedule put forth in February, with jury selection in the fall and opening statements on Oct. 26 or Nov. 2.

The federal hearing came just under a month after a New York judge told Mangione's defense to be ready for the state trial on June 8. Judge Gregory Carro had floated the idea of delaying it only if the federal trial was delayed first.

Bailiffs escorted Mangione out of that hearing after an unexpected outburst in which he claimed to be the victim of double jeopardy.

"It’s the same trial twice," he said. "One plus one is two. Double jeopardy by any common sense."

Both courts have dismissed the most severe counts, but Mangione still faces life in prison if convicted. He also faces lesser charges in Pennsylvania, where police arrested him in a McDonald's restaurant, in connection with the case.
