Muslim Speaker for Obama Inaugural Prayer Tied to Terrorists

Muslim scholar, Ingrid Mattson, president of the Islamic Society of North America, has been chosen to speak at Obama's inaugural prayer service. Mattson is the leader of a group that federal prosecutors say has ties to terrorists. Mattson is also a professor of Islamic studies at Hartford Seminary in Hartford, Connecticut.

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.
