Looks like Mother Jones has up a lengthy article on the Oathkeepers. I just started reading it.

Oath Keepers and the Age of Treason

Founded last April by Yale-educated lawyer and ex-Ron Paul aide Stewart Rhodes, the group has established itself as a hub in the sprawling anti-Obama movement that includes Tea Partiers, Birthers, and 912ers. Glenn Beck, Lou Dobbs, and Pat Buchanan have all sung its praises, and in December, a grassroots summit it helped organize drew such prominent guests as representatives Phil Gingrey and Paul Broun, both Georgia Republicans.

There are scores of patriot groups, but what makes Oath Keepers unique is that its core membership consists of men and women in uniform, including soldiers, police, and veterans. At regular ceremonies in every state, members reaffirm their official oaths of service, pledging to protect the Constitution—but then they go a step further, vowing to disobey “unconstitutional” orders from what they view as an increasingly tyrannical government.

Oath Keepers collaborates regularly with like-minded citizens groups; last Fourth of July, Rhodes dispatched speakers to administer the oath at more than 30 Tea Party rallies across America. At last fall’s 9/12 march on Washington, he led a contingent of Oath Keepers from the Capitol steps down to the Vietnam Veterans Memorial. Afterward, Oath Keepers cohosted a banquet with the hawkish Gathering of Eagles. This February, a member of the group organized a Florida Freedom Rally featuring Joe the Plumber and conservative singer Lloyd Marcus. (Sample lyrics: Mr. President! Your stimulus is sure to bust / it’s just a socialistic scheme / The only thing it will do / is kill the American Dream.)

Rhodes has become a darling of right-wing pundits. In a column last October, Pat Buchanan predicted that “Brother Rhodes is headed for cable stardom.” Glenn Beck has cited the group as a “phenomenal” example of the “patriot revival movement,” while Lou Dobbs declared that its platform “should give solace and comfort to the left in this country.” Conspiracy-radio king Alex Jones even put an Oath Keepers segment, including footage of the Lexington speech, on his hit DVD Fall of the Republic. “I can’t stress enough how much your organization is scaring the globalists,” he told Rhodes on his show.

As of mid-January, according to Rhodes, Oath Keepers had at least one chapter in every state and was adding dozens of members daily. Some 14,000 people had signed up as members on the Oath Keepers website while more than 15,000, including dozens of military recruiters, had done so on Facebook. And that doesn’t include those who, fearing reprisal, do their networking offline. Volunteers are in the process of sending out some 1,000 “constitutional care packages” complete with Oath Keepers patches to soldiers serving overseas.
