This is the oath that witnesses before the House Committee on Oversight and Government Reform requires of its witnesses, when those witnesses are sworn (and if one witness is required to be sworn, they all must be) (scroll to Rule 9, para (g)). It’s not the same oath for all committees, but it’s typical.
Do you solemnly swear or affirm that the testimony that you are about to give is the truth, the whole truth, and nothing but the truth, so help you God?
I mention this because it turns out
Then-Deputy Commissioner Steven Miller wrote in an email in June 2012, about a month before a House Ways and Means subcommittee hearing….
“I am beginning to wonder whether I should do [the hearing] and affirmatively use it to put a stake in politics and c4 [regarding IRS targeting of conservative organizations applying for 501(c)(4) status].”
Miller also was never directly asked about the targeting. That removes the legal aspect of perjury: Miller would seem not to have perjured himself.
But morally? Yew betcha.
