Oath Keepers

Oath Keepers is an American organization associated with the anti-government patriot movement. It encourages members—some of whom are current and former U.S. military and law enforcement officers,—not to obey orders which they believe would violate the United States Constitution. The group is best known for its controversial presence in Ferguson, Missouri during protests and unrest in the city, and during which its members were armed with semi-automatic rifles and were described as a far-right militia group by the media. The group espouses a number of false conspiracy theories and scam legal theories associated with the sovereign citizen movement and the white supremacist posse comitatus movement's Richard Mack.

The organization describes itself as 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.” The Anti-Defamation League describes the group as "heavily armed extremists with a conspiratorial and anti-government mindset looking for potential showdowns with the government".
