A Minneapolis mob of leftists hurled projectiles at James O'Keefe and the O'Keefe Media Group team on Saturday as they documented the ICE-involved shooting.

James O'Keefe also received a death threat from a leftist who was stalking him and tailing his vehicle.

DHS law enforcement officers were conducting a targeted operation in Minneapolis against an illegal alien wanted for violent assault when an armed man approached Border Patrol officers, the DHS said.

The armed man, identified as 37-year-old Alex Jeffrey Pretti from South Minneapolis, was fatally shot by a federal agent.

James O'Keefe posted a screenshot of the death threat.

"You have 1 hour to leave or you're dead," the message read.
