Unlike some other extremist organizations, the National Socialist Movement (NSM) actively works with other white supremacist groups ranging from racist skinheads to the Klan to other neo-Nazi groups.

The NSM’s August 2010 march and rally in Knoxville, Tennessee, attracted an unusually diverse crowd of white supremacists.   In addition to the NSM, the group of approximately 80 included members of the United Knights of Tennessee Order of the Ku Klux Klan, the neo-Nazi SS Action Group, Volksfront, a neo-Nazi organization and the Confederate Hammerskins, a racist skinhead group.  

In April 2009, the NSM celebrated Hitler’s birthday by holding public rally under the Gateway Arch in St Louis, Missouri.  In addition to NSM members there were several Klan members, Hammerskins, and members of the Aryan Nation’s Prison Ministry.  Later that same weekend the NSM collaborated with the Illinois National Socialist Front (INSF) to protest the opening of the Illinois Holocaust Museum in Skokie, Illinois.  Also present was Art Jones, a long time pro-white activist, former member of the white supremacist National Socialist White People’s Party, and a frequent candidate for elective office.

During a September 2009 protest in Belleville, Illinois, the NSM was joined by several Klansmen, members of the INSF, and William DeBoer, founder of the Illinois-based White Boy Society.  The protest stemmed from what the group alleged was a hate crime against a white victim by black assailants.

NSM members also attended the “National Alliance 2007 International Holocaust Revisionist Conference” at the National Alliance property in Hillsboro, West Virginia. Speakers at the event included Willis Carto, anti-Semitic propagandist and publisher of American Free Press and The Barnes Review, a Holocaust denial publication; Arthur Butz, Holocaust denier and associate professor of electrical engineering at Northwestern University, and Edward Fields, a long-rime white supremacist.

Speakers at an April 2006 event in Lansing, Michigan included Klan members and white supremacist Hal Turner. Also in attendance was veteran white supremacist Tom Metzger. Two months later, a joint Klan and NSM event occurred at the Antietam Battlefield in Sharpsburg, Virginia.

At a June 2005 rally in Yorktown, Virginia, the NSM teamed up with the American Thule Society, a white supremacist group, in an event to “honor our brave American forefathers.” Speakers included representatives from both groups. The NSM reported that the event was attended by members from various white supremacist groups including the Old Glory Skins, Aryan Nations, KKK, Creators, Teutonic Knights, and American Front. After the rally, KKK Imperial Wizard Virgil Griffin's organization, Cleveland Knights of the Ku Klux Klan, emailed Jeff Schoep to let him know that the Klan members that had been sent to the rally in support of the NSM had been turned away by police.
