"Founded by Stewart Rhodes, Oath Keepers is made up of military personnel, police officers, and other citizens who have sworn an oath to 'preserve, protect, and defend the Constitution of the United States against all enemies both foreign and domestic.' This is the same oath given to Congressmen, Senators, and Presidents. And, interestingly enough, the letter containing the threat is aimed directly at Oath Keepers.
But why would Codrea be the recipient of the letter?
Oath Keepers is dedicated to keeping the oath to guard the Constitution in light of the fact that so many within government and law enforcement circles have broken it. The dedicated men and women of Oath Keepers, however, have pledged with their own lives to keep that oath even if they are ordered to break it. The concept is based upon the premise that they are sworn to uphold The Constitution, even if it means disobeying misguided and/or malevolent superiors who give orders that are tantamount to a direct assault on that Constitution. After all, the oath is to uphold the Constitution. There is no oath to obey any law or any order that violates the Constitution."
