Abdin pleaded guilty in August to attempting to provide material support to a terrorist organization. He was arrested at Charleston's airport in 2017 as he tried to board a plane for Jordan. Authorities say Abdin told an agent posing as an Islamic State recruiter he wanted to torture an American.
At age 16, authorities say Abdin talked about robbing a gun store to get weapons to kill soldiers. He was arrested, pleaded guilty, and a parole board agreed to his early release after a year.
