Omar Faraj Saeed Al Hardan, 24, who was living in Houston, has been charged in a three-count indictment alleging that he attempted to provide material support to the Islamic State, or ISIL. Prosecutors say he received machine-gun training from the terror group.
In a separate filing, Aws Mohammed Younis al-Jayab, 23, of Sacramento, was charged with making false statements involving his alleged travel to war-torn Syria to assist terror organizations.
Al Hardan entered the United States as an Iraqi refugee in November 2009 and was granted legal permanent residence status in 2011.
In addition to providing support to ISIL, Al Hardan also is charged with unlawfully obtaining resident status here.
