A California man has been charged by federal authorities for threatening to kill District Attorney Fani Willis "like a dog" because of her prosecution of former President Donald Trump, the U.S. Attorney in Georgia announced.

Marc Schultz, 66, of Chula Vista, was indicted by a federal grand jury in Atlanta on charges of transmitting interstate threats to injure Willis, the district attorney in Fulton.,  the U.S. Attorney's Office in the Northern District of Georgia said in a statement on Friday.

Schultz on two occasions last October posted videos on YouTube threatening Willis "with violence and murder," including that she "will be killed like a dog," the statement said.

"Sending death threats to a public official is a criminal offense that will not be tolerated," U.S. Attorney Ryan K. Buchanan said in the statement.  

"Our office will continue to diligently coordinate with our federal, state, and local law enforcement partners to help protect public officials while performing their duties and who deserve to do so free from threats of harm and intimidation," he added.

Schultz is scheduled to be formally arraigned in Atlanta in June. 

Trump and his allies have been accused of attempting to overturn the results of the 2020 presidential election in Georgia.  

Trump is currently under a gag order regarding jurrors and witnesses in his ongoing hush-money trial in Manhattan to protect them from intidimidation and threats from his supporters.
