The most comprehensive survey of Americans who’ve been charged with attempting to help ISIS finds that none of the 68 are Syrian or Syrian-American and that only three were refugees of any kind.

“ISIS Cases in the United States,” compiled by Fordham University Law School’s Center on National Security, notes instead that to date four out of five U.S. residents charged with supporting ISIS are American citizens and almost two-thirds are U.S.-born.

Moreover, the three ISIS sympathizers who were killed in attempts to carry out attacks in the U.S. — in Texas and Boston — were all U.S.-born citizens. Two were African-Americans and the other the son of a Catholic nurse and a Pakistani-American engineer.

“In the ISIS cases, there is NO trend suggesting the involvement of refugees … or Syrians,” said Karen Greenberg, director of the Center.
