The View Bill O'ReillyFireworks erupted on the set of 'The View' today when hosts Whoopi Goldberg and Joy Behar left the set during an interview with Bill O'Reilly while discussing the proposed "Ground Zero mosque."

"The mosque down here on 9/11. That's inappropriate," O'Reilly said of the planned Islamic community center being built near the site of the former World Trade Center.

"Sure, they have a right to do it," he continued. "But it's inappropriate because a lot of the 9/11 families who I know, say, 'Look, we don't want that.'"
