From Obama’s speech to the Congressional Hispanic Caucus on September 15, 2010:

“So let me close by saying this. Long before America was even an idea, this land of plenty was home to many peoples. To British and French, to Dutch and Spanish, to Mexican — (applause) — to countless Indian tribes. We all shared the same land. We didn’t always get along. But over the centuries, what eventually bound us together — what made us all Americans — was not a matter of blood, it wasn’t a matter of birth. It was faith and fidelity to the shared values that we all hold so dear. We hold these truths to be self-evident, that all men are created equal, endowed with certain inalienable rights: life and liberty and the pursuit of happiness.”

But this is what  the U.S. Declaration of Independence really says:

“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.”

For a man who has a team of speech writers who are likely brilliant and check their sources, I can’t imagine that this omission was an accident…
