The Philadelphia district attorney suing Elon Musk and his America super PAC for its $1 million giveaways asked the court Wednesday to increase security at a planned hearing in the case Friday—and asked for Musk to appear in person—as the DA said he’s received violent threats from Musk’s supporters over the lawsuit.

Top prosecutor Larry Krasner has asked for additional security at an upcoming hearing in his suit against Musk, saying some posts on social media are “inviting political violence.”

Philadelphia’s district attorney asked a state judge on Monday to shut down tech billionaire Elon Musk’s controversial $1 million giveaway to registered voters, calling it an “illegal lottery scheme.”
