A US man posting content online as "Mr Satan" has been charged with threatening to assassinate President Donald Trump and other government officials, the Department of Justice announced.
Shawn Monper, 32, was detained and charged in a federal criminal complaint with "making threats to assault and murder" Mr Trump and other US officials, including Immigration and Customs Enforcement (ICE) agents.
In a statement, the DOJ said the FBI received an emergency message about threats posted on YouTube by a user who identified himself as "Mr Satan," whose internet activity was determined to correspond with Mr Monper's residence.
Mr Monper is coincidentally from Butler, Pennsylvania, where Mr Trump was nearly assassinated during a campaign rally last July.
Shortly after Mr Trump's inauguration in January, Mr Monper obtained a firearms permit and commented from his account that he had "bought several guns and been stocking up on ammo since Trump got in office," the DOJ said.
On 17 February he wrote: "Nah, we just need to start killing people, Trump, Elon, all the heads of agencies Trump appointed, and anyone who stands in the way," referring to Mr Trump's billionaire adviser Elon Musk.
"Remember, we are the majority, MAGA is a minority of the country, and by the time it's time to make the move, they will be weakened, many will be crushed by these policies, and they will want revenge too. American Revolution 2.0," he said, according to the DOJ.
Then on 4 March, in a YouTube video titled "Live: Trump's address to Congress," Mr Monper said he was "going to assassinate him myself," the DOJ added.
Mr Monper hails from Butler township, scene of a shooting last 13 July that nearly took Mr Trump's life, when a would-be assassin's bullet grazed the Republican's ear at an outdoor campaign rally. One person was killed and three were injured.
"Rest assured that whenever and wherever threats of assassination or mass violence occur, this Department of Justice will find, arrest, and prosecute the suspect to the fullest extent of the law and seek the maximum appropriate punishment," Attorney General Pam Bondi said in the statement.
A detention hearing is scheduled for 14 April.
