The Anne Frank Center is calling for White House press secretary Sean Spicer to be fired after his Tuesday comments claiming Adolf Hitler did not use chemical weapons during World War II.



In a statement posted on Facebook, the center's executive director blasted Spicer, saying the White House spokesman "lacks the integrity" to serve in his post.



"On Passover no less, Sean Spicer has engaged in Holocaust denial, the most offensive form of fake news imaginable, by denying Hitler gassed millions of Jews to death," Steven Goldstein said in a statement.



"Spicer's statement is the most evil slur upon a group of people we have ever heard from a White House press secretary." He added: "President Trump must fire him at once."

We applaud @POTUS for strong remarks on chemical attack in Syria, but the answer requires him to drop his refugee ban. #NeverAgain to anyone — AnneFrankCenter(US) (@AnneFrankCenter) April 5, 2017

No chemical weapons. No refugee ban. No #Islamophobia. @POTUS @realDonaldTrump all three are required for a humanitarian response. — AnneFrankCenter(US) (@AnneFrankCenter) April 5, 2017
