Oath Keepers

From their website: “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.”

However, the Department of Justice describes the Oath Keepers as, "an anti-government, right-wing political organization committed to supporting and defending their interpretation of the U.S. Constitution against all enemies, both foreign and domestic."
