Prosecutors in the case against Luigi Mangione have expressed concerns over what they describe as overly invasive tactics by the defense team, aimed at probing jurors’ personal lives.
In a filing submitted on Monday, federal prosecutors addressed a series of questions proposed by Mangione’s defense attorneys, which have not yet been disclosed to the public. Deputy U.S. Attorney Sean Buckley criticized some of these questions, labeling them as “unnecessarily intrusive.” Mangione is facing charges for the alleged assassination of UnitedHealthcare CEO Brian Thompson.
Buckley specifically took issue with a particular question from the defense, which he argues encroaches too deeply into the personal lives of potential jurors.
Mangione appeared at an evidentiary hearing for the murder case of UnitedHealthcare CEO Brian Thompson, held at the Manhattan Supreme Court in New York on December 18, 2025.
“The disputed Question 14(a) is problematic,” Buckley noted, highlighting that it seeks detailed personal information from jurors, including the ages, genders, occupations, and educational backgrounds of their children, which he deemed excessively intrusive.

“This question is inappropriate because a juror’s religious practices have no bearing on the juror’s fitness to serve,” Buckley wrote.
One of the other questions opposed by federal prosecutors asks if potential jurors have been “targeted” or “investigated” in connection with a criminal matter, which Buckley says “is not appropriate.”
“Where proposed questions are duplicative, seek highly personal information unrelated to juror impartiality, or risk embedding advocacy and legal argument into the voir dire process itself, this Court should decline to include them,” Buckley wrote.
Mangione faces state and federal charges in connection with his alleged assassination of Thompson. His federal trial is currently scheduled to begin in October.

In April, a judge overseeing Mangione’s state court case moved the trial date from June 8 to Sept. 8. If convicted, he faces life in prison.
