Christie's advice to Spicer: 'Don't bring up Hitler. Ever'

White House press secretary Sean Spicer pauses while talking to the media during the daily press briefing at the White House in Washington, Tuesday, April 11, 2017. Spicer discussed Syria, Trump's 2016 tax returns, the Easter Egg Roll and other topics.

Gov. Christie had some advice Wednesday for White House press secretary Sean Spicer: "Don't bring up Hitler. Ever."

In his daily briefing Tuesday, while criticizing Syrian President Bashar al-Assad, Spicer said Adolf Hitler "didn't even sink to using chemical weapons." He did not immediately acknowledge Hitler's use of gas chambers to exterminate Jews during the Holocaust.

“There should be a general rule for anybody involved in public life. ... Don’t bring up Hitler. Ever,” Christie said on Fox & Friends. “There’s no winning in bringing up Hitler.”

“Unfortunately for Sean, he got carried away with himself,” Christie said. Given Spicer’s experience, the governor said, “he should know better.”

Spicer apologized Tuesday for his comments, saying he “mistakenly made an inappropriate and insensitive reference to the Holocaust, for which there is no comparison.”

At his press briefing, Spicer made the remark about Hitler's not "sinking" to using chemical weapons in contrasting his actions with the gas attack on Syrian civilians last week.

Asked during the briefing about that statement, Spicer said: “I think when you come to sarin gas, there was no -- he [Hitler] was not using the gas on his own people the same way that Assad is doing.” He also said Hitler “brought them into the Holocaust center, I understand that," apparently referring to death camps.

Asked on Fox & Friends Wednesday about the “mainstream media” and its focus on the press secretary’s comments, Christie continued to blame Spicer.

“This is the game we play. If you’re the White House press secretary, you know that,” Christie said. “He deals with the mainstream media every day. … But the fact of the matter is that you never bring up Hitler. That’s a good rule.”

Christie also again urged President Trump’s administration to suspend federal regulations allowing airlines to bump passengers, after this week’s incident involving a passenger dragged off an overbooked United Airlines flight.

“Let’s hope they’re listening,” host Steve Doocy said as he ended the interview. Trump is known to watch the program, at times responding on Twitter.

“We know they listen to Fox & Friends. Come on,” Christie said.
