"I do solemnly swear (or affirm) that I will support the Constitution of the United States."
The text now reads:
"I, ________, do solemnly swear (or affirm) 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 that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God."
This office, much more specific and lengthy than the original, is now used by every federal office investiture except for the office of the President.
