Statement from Steven Goldstein, executive director of the Anne Frank Center for Mutual Respect:

"On Passover no less, Sean Spicer has engaged in Holocaust denial, the most offensive of fake news imaginable, by denying Hitler gassed millions of Jews to death. Spicer's statement is the most evil slur upon a group of people we have ever heard from a White House press secretary. Spicer now lacks the integrity to serve as White House press secretary, and President Trump must fire him at once."
