White House press secretary Sean Spicer faced major social media criticism Tuesday after referring to concentration camps as “Holocaust centers” while walking back his claim that Nazi leader Adolf Hitler did not use chemical weapons.

Spicer first drew attention at Tuesday’s press briefing when he criticized Syrian President Bashar Assad’s use of chemical weapons on his own people by comparing him to Hitler.

“You had someone as despicable as Hitler, who didn’t even sink to using chemical weapons,” he said.

{mosads}Many, including a journalist in the press briefing, were quick to point out that Hitler used gas chambers to kill millions of Jewish people during the Holocaust. Spicer attempted to walk back his statement.

“When it comes to sarin gas, [Hitler] was not using the gas on his own people the same way that Assad is doing,” Spicer said.

“I understand your point. Thank you. I appreciate that. He brought them into the Holocaust centers, I understand that. I was saying in the way that Assad used them where he went into town, dropped them into the middle of town. I appreciate the clarification. That was not the intent.”

His reference to concentration camps as “Holocaust centers” drew immediate attention and criticism on social media. Shortly after the press briefing ended, “Holocaust centers” was trending on Twitter with more than 2,000 tweets. 

Did Spicer just refer to a Nazi extermination camp as a “Holocaust Center”? https://t.co/IQYvdaO3nt

Here’s the followup @PressSec comment about Assad & Hitler. I’ve rewound it 4 times. Did he say “Holocaust center?” https://t.co/oVQAWmm570

“Concentration Camps”
“Holocaust Centers”
“The Shops at Holocaust Village”

Honestly, “holocaust centers” is weirder than anything else he said.

Look, the Press Secretary may have just called concentration camps “holocaust centers,” but at least he didn’t do it during Passover.

Sean Spicer would show up to the gallows & be like “does anyone know when the neck hugging ceremony starts?”

PEPSI: we’re the worst

UNITED: no, we’re the worst

SEAN SPICER: hold my beer

If I said what Sean Spicer said in public or private, I would be fired from my comms job, immediately, and deservedly so.

HEY UNITED, YOU SHOULD DRAG SEAN SPICER AWAY FROM THIS PRESS BRIEFING

— Quinn Sutherland (@ReelQuinn) April 11, 2017

Spicer’s internal monologue: “Hmm, I need to argue that Assad is bad. Guess it’s time to downplay Hitler for some reason.”

whom could have predicted that Spicer talking extemporaneously about Hitler would have turned out thusly

— Dave Itzkoff (@ditzkoff) April 11, 2017

Wow Spicer’s lucky there’s not some Jewish holiday about the liberation from the forces of death on right now.

I hope SNL does a skit where Air Force One is overbooked, and either Sean Spicer or Kellyanne Conway is dragged off the plane. #united

Sean Spicer says Hitler didn’t use chemical weapons….do gas chambers to kill millions of Jews count? Yikes…

— Katie Pavlich (@KatiePavlich) April 11, 2017

I mean say what you want about Hitler. He killed 6 million people without the use of nerve agents, except that whole gas chamber thing…

This is actually worse. German Jews weren’t German people? They were… what? Aliens like Nazis claimed? https://t.co/3slkognoN3

Does anyone genuinely think @seanspicer doesn’t know what happened in the Holocaust?
No.
He jumbled his point, idiotically.
Move on.

Reason we know time travel won’t be invented in our lifetimes is that an older Sean Spicer didn’t suddenly appear and scream “Stop Talking!” https://t.co/fwFIgDDN05
