Sean Spicer has had to apologise for his comments comparing Assad to Hitler after he claimed Nazi Germany "didn't use chemical weapons".

His apology has backfired, causing angry comments from many people, who asked for him to be fired.

The Press Secretary said in his apology: "In no way was I trying to lessen the horrendous nature of the Holocaust, however, I was trying to draw a contrast of the tactic of using airplanes to drop chemical weapons on innocent people".

Stephen Pollard, the editor of the Jewish Chronicle, pointed out: "This isn't merely worse than original imbecilic comments.

"It's so shocking as to render Spicer unfit to continue. Jews were not 'innocent'?"
