The late-night host addressed the 78-year-old Republican politician's sharing of the "deranged" theory — which also claimed that Democrats were unaware of the former president's secret robot identity — during his opening monologue on Monday's episode ofJimmy Kimmel Live. "This is a theory that claims President Biden was cloned and replaced by a robot which, first of all, aren't robots and clones two entirely different things?" Kimmel asked. "Not in Trump's head they aren't. And secondly, I know Trump puts out this stuff as a smokescreen to hide the fact thathe's about to cut $600 billion dollars from Medicaid, but this is so deeply nuts," he continued. "How is this not on the front page of everything? The president of the United States is spreading deranged stories about his predecessor being a robot." ABC The comedian then shifted gears and redirected his criticism toward Trump's own party. "Hey, Republicans! Remember when you were very concerned about Joe might not have the mental acuity to be president?," he asked. "Come get your guy, because he thinks Biden was executed and replaced by a robotic clone." Kimmel continued, "I mean, if your dad was saying stuff like this, you'd start looking for an assisted living facility." He also noted that, if Biden truly is a robot, then whoever built him must be "very bad at building robots," adding, "I mean, if anyone was replaced by a robotic clone, it's Melania, right?" Although, he admitted, "A robot Joe Biden would make a pretty solid movie."

Kimmel was one of several late-night hosts who roasted Trump for sharing the theory last night. "In 2020, a secret cabal took out an old, slow Joe Biden and replaced him with... an older and slower Joe Biden,"Late ShowhostStephen Colbertjoked duringhis own opening monologue. "It's natural! It's just like when you trade in your rusted out '93 Honda Civic for an old man who loves trains." Seth Meyerspointed out duringLate Night's "Closer Look" segment that the theory was actually "great news for Democrats," adding, "It turns out that wasn'tJoe Biden who got stuck in a closet. It was a robot. And that happens to my Roomba all the time!" AndDaily ShowhostJon Stewartquestioned whether or not Trump was sober when he re-posted the claim. "You're saying that the Joe Biden, who doesn't even know where he is, is actually an incredibly advanced cloned robot?" He askedduring his monologue. "How much ketamine are you on?"
