Oath Keepers is a non-partisan association of current and formerly serving military, police, and first responders,  who pledge to fulfill the oath all military and police take to “defend the Constitution against all enemies, foreign and domestic.” That oath, mandated by Article VI of the Constitution itself, is to the Constitution, not to the politicians, and Oath Keepers declare that they will not obey unconstitutional orders, such as orders to disarm the American people, to conduct warrantless searches, or to detain Americans as “enemy combatants” in violation of their ancient right to jury trial.
