Late Saturday, President Trump shared a fringe conspiracy theory suggesting that former President Joe Biden was executed in 2020 and has since been replaced by “soulless, mindless” clones.

Trump didn’t address the credibility of the outlandish claim but did share a post on Truth Social from a relatively unknown user named llijh, who has less than 1,000 followers.

The post alleged that “#JoeBiden doesn’t exist—executed in 2020,” further adding that what people see are “#Biden clones, doubles, and robotic engineered soulless mindless entities,” suggesting that “#Democrats don’t know the difference.”

It is unclear why Trump shared the post, but he is known for trolling is critics on social media.

Trump last met Biden in person roughly five months ago during Inauguration Day, and shared the debate stage with him in both 2020 and 2024.

Since then, the president has frequently bashed his predecessor, who is now subject to renewed scrutiny over his mental acuity amid the release of “Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again.”

Trump has publicly suggested that Biden wasn’t fully in control of his administration, due to his use of autopen to sign key documents, something that Republicans on the House Oversight Committee are investigating.

“I think the autopen is going to become one of the great scandals of all time,” Trump said on Friday during an Oval Office event with tech baron Elon Musk.

“He’s been a sort of a moderate person over his life, and a smart person, but somewhat vicious person, I will say, if you feel sorry for him, don’t feel so sorry because he’s vicious.”

Congressional Republicans, led by House Oversight Committee Chairman James Comer (R-Ky.), have been investigating Biden’s health while he served as commander in chief.

Comer had summoned five confidants of Biden to answer questions about the 46th president’s health.

Biden’s team announced last month that he had been diagnosed with prostate cancer that had spread to his bones. Despite that, the former president is optimistic about his prognosis.

“We’re going to be able to beat this,” Biden told reporters in New Castle, Delaware on Friday, noting that he’s begun treatment. “We’re working on everything, it’s moving along. I feel good,”

“All the folks are optimistic.”
