The Air Force Academy has admitted they removed the phrase “so help me God” from three oaths in the 2012 edition of their official cadet handbook, Fox News has learned.

The revelation came after more than two dozen members of Congress sent a letter to Academy Supt. Lt. Gen. Michelle Johnson demanding that she explain why the phrase was removed. …

“The Constitution does not require that this phrase be scrubbed from the oath,” read the letter drafted by Rep. Jim Bridenstein (R-Okla.) and signed by 28 lawmakers. “The First Amendment to the United States Constitution prohibits the establishment of religion’ however, the inclusion of the phrase ‘so help me God’ in an oath of service does not rise to this level.”
