William Lintang Upham, the unhinged former Marine and write-in congressional candidate who posted a sick video declaring President Donald Trump the “Antichrist” and saying he “must be killed,” has been arrested.
As The Gateway Pundit reported on Wednesday, Upham, a medically retired former Marine 1st Lieutenant who worked as a prosecutor, posted a nearly seven-minute video to his X account in which he repeatedly referred to President Trump as the “anti-Christ” and a “false Messiah” before explicitly calling for his assassination.
He claimed he reached a “turning point” in his campaign after realizing “our country is broken” and that “we are led by a president who’s the enemy of God.”
Upham tied his hatred to President Trump’s recent criticism of Pope Leo XIV and an AI-generated image Trump posted depicting himself in a Jesus-like pose. “He is nothing like Jesus Christ,” Upham said.
He went further, calling it a “call to arms,” urging “God’s children” to “overthrow the Trump Administration on behalf of God,” and claiming Trump would be “killed and sent to hell.”

According to Jacksonville Sheriff’s Office inmate records, Upham, 35, was booked into Duval County Jail late Wednesday night, July 15, 2026, at 11:20 p.m. under Jail Number 2026015579 / JSO ID 892658.
He was held on a U.S. MARSHAL HOLD with the charge comment explicitly listed as “THREATS AGAINST THE PRESIDENT.”
The white male, 5’5”, 170 lbs, with black hair and brown eyes, was arrested by the Jacksonville Sheriff’s Office. Records show he was released on July 16, 2026, after a first appearance hearing scheduled for 1:00 p.m. today.
Federal charging documents obtained by Jacksonville Florida Times-Union paint an even darker picture.
According to the criminal complaint filed by a U.S. Secret Service agent, Upham posted videos recommending viewers work in pairs with semiautomatic rifles like AR-15s and ammunition “very effective at piercing body armor.” He described specific shooting patterns that would produce “a very high chance of killing the enemy.”
In an email to a reporter, Upham allegedly wrote: “I made this video in uniform to declare war against President Trump on behalf of God… I will kill President Trump at the time that God chooses… Our country must overthrow President Trump by the violent use of force and kill him.”
Upham, a former county court prosecutor in Jacksonville who is listed as not eligible to practice law in Florida, faces a federal charge for threats against the president, a crime that carries up to five years in federal prison, according to Jacksonville Florida Times-Union.
The U.S. Marine Corps and Acting Navy Secretary Hung Cao previously blasted Upham’s statements as “disturbing” and a violation of the oath he swore, making clear he no longer represents the Corps or its values.
The Jacksonville Sheriff’s Office booking record does not provide additional details regarding the federal investigation.
However, a U.S. Secret Service spokesperson told Fox News on Wednesday, “The U.S. Secret Service is aware of the comments made by a congressional candidate in Florida, and we investigate anything that can be perceived as a threat toward one of our protectees. Out of concern for operational security, we do not discuss matters of protective intelligence.”
