A California man has been charged with threatening to injure Fulton County District Attorney Fani Willis because of her prosecution of former President Donald Trump, authorities said.

Marc Shultz, 66, made his initial appearance in federal court in San Diego Thursday on charges of transmitting interstate threats. The Chula Vista resident was indicted by a federal grand jury in Atlanta in April.

The federal indictment alleges that Shultz posted multiple comments to two separate YouTube live stream videos on Oct. 4 and 5 of 2023. In one post, Schultz said Willis “will be killed like a dog,” the indictment said.

“Sending death threats to a public official is a criminal offense that will not be tolerated,” Ryan Buchanan, U.S. attorney for the Northern District of Georgia, said in a news release.

Schultz will be formally arraigned in Atlanta in June.

Willis has faced violent and racist threats over her racketeering prosecutions of Trump and Atlanta rapper Young Thug. The threats have prompted her to move out of her home and travel with a security detail.

“I thank U.S. Attorney Ryan Buchanan, his staff and the FBI for believing the life of an African American elected official has value and for their diligent efforts in ensuring the safety of myself, my staff, and our families,” Willis said in a statement.
