Donald Trump is getting pushback on Sunday on his latest conspiracy theory from an unlikely source: his own MAGA supporters.

The former president earlier in the day claimed that Vice President Kamala Harris was faking her huge crowd sizes by using AI. The claim was ranked as "just false" by CNN, and one lawmaker said it made Trump unfit to be president.

When Trump posted the claim on his own social media network, Truth Social, some of his own supporters encouraged Trump to back off.

One user, @Trumpbobo, said, "You realized that there is a video right that so otherwise shows."

Another MAGA fan, @Gobbyrocks, stood up to Trump:

"It's not fake, Trump. Please fire your disastrous advisors immediately before we lose this election!"

@Magahlahgo replied, "Are you ever going to talk about what you plan on doing if you win? Nobody cares about her crowds."

@Cordlopez took a serious tone, saying, "Please shut the f--- up and get focused."

@Witness023 replied, "No. Consult with a good expert on this. They are going to make us look dumb."

@Deplorable59 also told Trump to "STFU about the crowd size."

"She's getting bigger crowds now face that fact. You're gonna lose this!" the user wrote on Sunday. "Stop with this bulls--- - get out on the road. Talk to the people-don't talk about her personally. Talk about the issues and what you will do to change things. You're our only hope - you gotta stop screwing it up!"

Karlyn Borysenko also replied, saying, "I want you to win but you have got to start hinging back into reality and stop listening to anyone who lies to you about Kamala's campaign."

"This is a video that aired live of the event," she wrote. "It is real. The photos are being generated from a parody account."

Conservative influencer Ian Miles Cheong echoed those sentiments.

"Kamala’s crowd at the airport was in fact real," he wrote. "You can claim they’re paid actors or that they were just there for a concert but they are definitely not AI."
