Newt Gingrich's campaign manager, his spokesman and a half dozen other staffers have resigned, but he says he's forging ahead.

“I am committed to running the substantive, solutions-oriented campaign I set out to run earlier this spring,” Gingrich wrote on his Facebook page. “The campaign begins anew Sunday in Los Angeles.”

Gingrich is the keynote speaker on Sunday night at a Republican Jewish Coalition dinner at the Beverly Hilton. He also plans to participate in the presidential debate in New Hampshire on Monday.

So what gives? The staff may have been fed up by Gingrich's long vacation in Greece, with Twiggy among those onboard.
