Slight difference
“By his own admission, Laatsch betrayed his oath..."
Not an oath, at least not in front of a government official/agent. It's a lifetime NDA (contract) between you (citizen) and the US federal government -- the standard "take everything to your grave (even if it's leaked or declassified)" agreement. Enforceable in court with criminal penalties, yes, but not an actual oath like courtroom swearing-in, the Presidential / Congressional oaths of office, oaths to defend the Constitution for those entering the military, or citizenship ceremonies with a judge.
(Anon, obviously. Don't ask. Go away.)
