Geraldo Rivera exploded at fellow Fox News co-host Andrea Tantaros on Monday after she challenged his criticism of Israel, telling her she "should be ashamed" of herself for questioning him, a "dyed-in-the-wool Zionist."
Rivera had been blasting Israel for the high number of civilian deaths since the start of its offensive in Gaza, including for a strike on a United Nations facility where people had been sheltering.
"They put these kids in a school, they put weapons deliberately in a school, then Israel strikes and people like you get up and defend a terrorist organization," Tantaros said on Fox News' "Outnumbered."
"What is a 'person like me'?" Rivera demanded.
"It's an apologist for a terrorist organization," Tantaros said.
"You should be ashamed of yourself for saying that to me of all people," Rivera said. "There's a Jewish star tattooed on my hand, I am a dyed-in-the-wool Zionist, I would die for Israel, this is appalling."
Tantaros interjected, "Whose side are we on?"
"Whose side are we on when there are 1,800 dead civilians and women and children are bleeding on camera, and you are not moved by that?" Rivera said.
The back-and-forth went on, with Rivera ultimately declaring, "Israel is alone in the world and attitudes like yours will make it isolated more and more."
