The controversial comedian appeared Saturday at a Turning Point USA’s AmericaFest in Phoenix billed by the conservative group as “​the largest celebration of our constitutional rights and freedoms.”

She took the stage with a wobble and began by declaring that she’s “all in for President Trump.”

“I just wanna say that, I’m just all in… Because I know if I ain’t all in they’re going to put my ass in a gulag. If he loses I know what they’re gonna do,” she yelled.“And I don’t wanna go to a reeducation camp and have to give all my money to a bunch of losers that never know how [to] get a job. I don’t care about them,” she ranted.

“If we don’t stop these horrible communists, do you hear me? I’m asking you to hear me!” Barr, 70, bellowed.

“Stalinists! Communists! With a huge helping of Nazi fascists thrown in. Plus one caliphate to replace every Christian democracy on Earth now! Occupy! Do you know that?” she went on.

After first cheering Barr’s address wildly, the crowd grew increasingly quiet as she continued her bizarre speech.

“I just want the truth — we deserve to hear the truth! That’s what we want! We want the truth!” she continued.

“We don’t care which party is wrong, we know they’re both nothing but crap! They’re both on the take! They’re both stealing us blind! We just want the truth about everything we fought and died and suffered to protect!” Barr added.

Video of her speech shared on X by Ron Filipkowski, editor-in-chief of media outlet MeidasTouch, has been viewed more than 2 million times.

“Roseanne Barr appears to have had several cocktails and is screaming about Stalinists and communists and Nazis and by the time she gets to a Muslim Caliphate taking over the world the crowd is left in stunned silence,” he captioned the post.

The four-day AmericaFest takes place in various locations across the US and Rolling Stone described this year’s event in Phoenix as “infested with antisemitism.”

On Saturday, it wrote that many of the speakers, including Barr, have expressed a “distrust, distaste, or outright hatred of Jewish people.”

Kirk, the founder of Turning Post USA, also has been accused of making antisemitic claims on his podcast.

On Saturday, it wrote that many of the speakers, including Barr, have expressed a “distrust, distaste, or outright hatred of Jewish people.”

The comedian’s speech was met with widespread ridicule online.

“Poor Roseanne… she coulda retired and kept her mouth shut, lived like a queen on her royalties and kept the legacy of her career intact,” one user wrote on X. “But she had to embrace Trump and everything Trump touches…”

Another wrote: “The power of free speech is that it permits idiots and flat-earthers to identify themselves,” while a third pointed out that “absolutely no one in that room knew what ‘caliphate’ means.”

But some also expressed support for the controversial comic.

“She tells it like it is, gotta love that,” one user said.

“We love this from Roseanne!!” another added.

Barr did not immediately respond to The Post’s request for comment.
