Here is a report about the "Oath Keepers" group:
I am not a member of this group, but as a former member of the US armed services (enlisted and officer), I have taken the oath several times.
What oath, you may ask?
US Constitution, Article VI
3: The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.
It's instructive to note that most current and former members of the US armed services appear to take their oaths seriously, while most members of the executive branch, Congress, and the courts don't seem to. Yet somehow "oath keepers" are considered a threat to the nation, while "oath breakers" are running this country (into the ground, I might add).
Those of you who still are rational someday will regret allowing this to happen. The rest of you can go to hell. I hope you're happy with the mess you have created.
