Oath Keepers is an American nonprofit organization that advocates that its members (current and former U.S. military and law enforcement) disobey any orders that they are given if they believe they violate the Constitution of the United States.
The Oath Keepers were founded on March 2009 by Stewart Rhodes and incorporated in Las Vegas, Nevada as a non-profit corporation. Rhodes is a Yale Law School graduate, a former US Army paratrooper, and a former staffer of Congressman Ron Paul. The Oath Keepers as a group have grown to include chapters in many states across America.
In the Southern Poverty Law Center's (SPLC) 2009 report The Second Wave: Return of the Militias, Larry Keller, a writer for the SPLC, wrote that the Oath Keepers "may be a particularly worrisome example of the Patriot revival." Keller described Richard Mack, an Oath Keeper, as a "longtime militia hero" and quoted him as having said, "The greatest threat we face today is not terrorists; it is our federal government… One of the best and easiest solutions is to depend on local officials, especially the sheriff, to stand against federal intervention and federal criminality." Mack, a former sheriff, responded by denying the claims, saying "I have had no contact with any militia group and have never been a member of any militia." Rhodes, who is one quarter Mexican and part Native American has also disputed the SPLC claim of racism. Writing in The American Conservative Jesse Walker commented that "Not every Oath Keeper would appreciate the comparison, but the group has more in common with those dissidents of the ’60s who refused to go to war than with any paramilitary cell."
Lou Dobbs talked with Rhodes on his radio show and criticized the SPLC for "perpetuating the same kind of intolerance it claims to condemn." On Hardball with Chris Matthews, Matthews and Rhodes discussed both the SPLC report and issues involving the Oath Keepers and extremists. said "Oath Keepers, depending on where one stands, are either strident defenders of liberty or dangerous peddlers of paranoia.” Buchanan himself concluded that "America was once their country. They sense they are losing it. And they are right."
