A former Army National Guard member was arrested Sunday on charges of attempting to provide material support for ISIS, the FBI announced. Mohamed Bailor Jalloh was allegedly conspiring to help carry out a terror attack on U.S. soil, prosecutors allege. Jalloh is said to have told an undercover FBI agent that he had recently returned from Africa where he met with ISIS members in Nigeria and was inspired by former al Qaeda leader Anwar al-Awlaki, who was killed in a U.S. airstrike in Yemen in 2011.
