Federal Executive and Legislative Branch Oaths

Federal Executive and Legislative Branch Oaths (From Wikipedia.org)

In the United States, the oath of office for the President is specified in the Constitution (Article II, Section 1):

"I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."[64]

The oath may be sworn or affirmed (in which case it is called an affirmation instead of oath). Although not present in the text of the Constitution, it is customary for modern presidents to say "So help me God" after the end of the oath.

For officers other than the President, the expression "So help me God" is explicitly prescribed, but the Judiciary Act of 1789 also explains when it can be omitted (specifically for oaths taken by court clerks): "Which words, so help me God, shall be omitted in all cases where an affirmation is admitted instead of an oath."[65]

The Constitution (Article VI, clause 3) also specifies:

The Senators and Representatives before mentioned, and the members of the several state legislatures, and all executive and judicial officers, both of the United States and of the several states, shall be bound by oath or affirmation, to support this Constitution; but no religious test shall ever be required as a qualification to any office or public trust under the United States.

At the start of each new U.S. Congress, in January of every odd-numbered year, newly elected or re-elected Members of Congress – the entire House of Representatives and one-third of the Senate – must recite an oath:

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.][66]

This oath is also taken by the Vice President, members of the Cabinet, federal judges and all other civil and military officers and federal employees other than the President.
