Luigi Mangione is expected to plead guilty in a federal stalking case.
Sources familiar with the matter say the plea hearing is scheduled for Friday, August 14, 2026.
The hearing will take place in Manhattan federal court.
Officials reportedly scheduled the court appearance hastily.
Mangione faces two federal counts of stalking.
It is not yet clear which specific charges the plea will address.
The charges relate to the December 2024 killing of UnitedHealthcare CEO Brian Thompson.
This federal proceeding remains separate from a state murder trial set for September 8.
Prosecutors allege Mangione ambushed and killed Thompson outside a Manhattan hotel during an annual investor conference.
