Just how dumb is this brain surgeon?

Dr. Ben Carson says the Pledge of Allegiance and other “founding documents” prove America is a Christian nation. He also says the motto, “In God we trust” proves the United States was founded as a Christian nation.

First of all, the Pledge isn’t a “founding document” and did not contain the phrase “under God” until 1954.

Secondly, “In God we trust” wasn’t made our motto until 1956.

Just how dumb is this “brain surgeon”?
