The men are suspected of trying to poison the food supply at Fort Jackson.
A source with intimate knowledge of the investigation, which is ongoing, told CBN News investigators suspect the "Fort Jackson Five" may have been in contact with the group of five Washington, DC area Muslims that traveled to Pakistan to wage jihad against U.S. troops in December. That group was arrested by Pakistani authorities, also just before Christmas.
Coming as it does on the heels of November's Fort Hood jihadist massacre, this news has major implications.
