President Trump’s spokesman Sean Spicer stunned the White House press corp on Tuesday when he said that Adolf Hitler — who massacred more than 6 million people in gas chambers — never used chemical weapons.

Responding to a question about Syria’s chemical weapons attack, Spicer said, “Someone who is [as] despicable as Hitler didn’t even sink to using chemical weapons.”

Minutes later, a reporter asked him to clarify his remarks.

“Quote, ‘Hitler didn’t even sink to the level of using chemical weapons.’ What did you mean by that?” the reporter asked.

Spicer seemed confused by the question and stuttered an answer: “I think when you come to sarin gas, there was no — he was not using the gas on his own people the same way that Assad is doing.”

Other reporters then mentioned the Holocaust, prompting Spicer to thank them for giving him a chance to clarify.

“There was no … he brought them into the holocaust center. [Not] the way Assad dropped the bombs into the middle of towns. I appreciate the clarification. That was not the intent,” he stuttered.

Twitter predictably went berserk over the embarrassing gaffe.

“HAPPENING NOW: Ivanka telling her dad Sean Spicer has to go.

LATER TODAY: Sean Spicer goes,” GOP pundit Bill Kristol wrote.

“Sean Spicer put more than a foot in his mouth when he said ‘Not even Hitler gassed his own people.’ With around six million exceptions!” snarked Harvard law professor Laurence Tribe

“@seanspicer as a tour guide: And here we have a Holocaust centre where a lot of Holocausting took place…,” added Eric Domond‏.

“Congratulations to @SeanSpicer on his new job at @united,” tweeted a used identified as civil rights pioneer Fredericks Douglass, referring to United Airlines public relations disaster after a doctor was dragged from a jet.

But he had his defenders as well.

“i dont know how you fire a guy who has one of the toughest jobs in DC for saying something that was obviously a innocent mistake,” wrote Charles Gasparino of FOX Business.
