This happened during the Congressional Hispanic Gala last week. The correct pertinent line in the Declaration is, "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed." Listen very closely at around the 22:30 mark.
A key phrase did he omit: "by their Creator". No, that's not just a minor slip-up. He has been omitting the Creator throughout his entire chequered career.
I didn't listen to the entire drivvel. I did take note how he complained about the Republicans blocking his "work". Oh, really? Last time I checked, the Dems controlled both houses of Congress. How is it that things are slowing a tad? Could it be some of the Dems doing that? Perhaps they see that Obama's policies are toxic to their political hides and are scurrying away from association with him like cockroaches scurry from light. It won't work, though, judging from recent events.
