"I do solemnly swear that I will support and defend the Constitution of the United States against all enemies, foreign and domestic, that I will bear true faith and allegiance to the same: that I take this obligation freely, without any mental reservation or purpose of evasion, and I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God."
