Republican presidential front-runner Newt Gingrich stood by his assertion that the Palestinians are an "invented people," drawing criticism from other GOP candidates.
"Is what I said factually correct? Yes. Is it historically true? Yes," Gingrich said during a GOP debate Saturday night in Iowa. "We are in a situation where every day rockets are fired into Israel while the United States -- the current administration -- tries to pressure the Israelis into a peace process."
