Congresswoman did not swear oath on a Bible

128. Actually it's a modified oath

that allows for those who object to more than the "So help me God" part.

The original standard federal oath of office:

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

(There may be extra stuff about confidentiality of the information observed or gathered relative to Title XIII and the Privacy Act that follow but the above is the general oath of office that all federal employees take)

Unless they object to: the word "swear" or "affirm" or refuses to sign the Oath for religious reasons, then the "Modified Oath" is used:

I, (name), do sincerely affirm that I will not violate, undermine or bear harm to the Constitution of the United States; that I will support and remain true to the mission of the same; that I take this obligation freely, without mental reservation or purpose of evasion; and that I will well and dependably discharge the duties of the office on which I am about to enter. I affirm.

And that's that. There may also be additional oaths of secrecy relative to specific committee appointments like defense and security that may ne administered upon the opening of new committee session but I don;t know what those might be but probably something similar only a little more specific using terms like "national security" and such. these oaths are good to know in case you ever need to confront a federal employee about their subordination in the service of ""we the people" as all officeholders who take this oath are, in officially, public servants.

So there you have it.
