Former Marine running for Congress says Trump is the Antichrist and 'must be killed' in shocking video

A Florida congressional candidate and former U.S. Marine is facing backlash after posting a video calling President Donald Trump "the Antichrist" and saying the president "must be killed."

William Upham, a Republican write-in candidate for Florida's 5th Congressional District who describes himself on X as a prosecutor "running to fix a broken political system," opens the nearly seven-minute video by saying he entered the race to restore bipartisanship, return power to the working class and "fix our broken political system."

The tone quickly shifts, however, as Upham says he has come to believe the country is "broken" and that America is engaged in a spiritual battle.

"We are led by a president who is the enemy of God," Upham says before citing Bible passages and discussing the oath he took as a Marine officer to defend the Constitution "against all enemies, foreign and domestic."

He then claims there is "no doubt" Trump is "the Antichrist."

"He is a false messiah, and he is your enemy and he must be killed," Upham says.

Later in the video, Upham urges viewers to question whether they are "worshiping a false idol" before concluding, "President Trump is the Antichrist. And he will be killed and sent to hell. God will prevail against evil."

The U.S. Marine Corps quickly condemned Upham, saying he was medically discharged on May 30, 2025.

"The Marine Corps is aware of the disturbing statements made by William Upham," the service wrote on X. "The comments made by Upham are a direct violation of the oath he swore to uphold and are not in keeping with the service's values."

The U.S. Secret Service also acknowledged the comments in a statement to Fox News Digital.

"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," a spokesperson said. "Out of concern for operational security, we do not discuss matters of protective intelligence."

Acting Navy Secretary Hung Cao also condemned the remarks, writing on X: "Unacceptable. William Upham is no longer a Marine and does not represent our values or ethos."

Fox News Digital reached out to the FBI, the White House and Upham's campaign for comment.
