But in 2007 and as recently as last July, federal prosecutors in Dallas filed court documents linking the Plainfield, Indiana-based Islamic society to the group Hamas, which the U.S. considers a terrorist organization.
The Islamic Society of North America, which describes itself as "the nation's largest mainstream Muslim community-based organization," is fighting its inclusion on a list of co-conspirators in the Dallas terrorism case against the Holy Land Foundation.
That foundation and five of its former leaders were convicted at a retrial in November of funneling millions of dollars to Hamas.
