Input: On Monday  a federal judge rescheduled proceedings for  Zakaryia Abdin  to January  according to documents filed in federal court. Both prosecutors and defense attorneys agreed to spend more time preparing  in part because some of the evidence is classified.
 Abdin  18   was arrested at Charleston's airport in March as  he  tried to board a plane for Jordan. Authorities said  he  told an undercover FBI agent posing as an Islamic State recruiter that  he  wanted to torture an American  and would attack a U.S. site if  he  couldn't get out of the country.
 Abdin  has pleaded not guilty and remains jailed on a charge of attempting to provide material support to a terrorist organization. If convicted  he could face up to 20 years in prison. His attorney has declined to comment.
The teen has been monitored for years. At 16  authorities said   he  talked about robbing a gun store to get weapons to kill soldiers as revenge for American military action in the Middle East.  He  was arrested before the robbery  pleaded guilty  and a parole board agreed to  his  early release after about a year in jail.
 Abdin  knew that authorities were still watching  him  â but apparently didn't realize  his  "recruiter" was a federal agent.
"We are most likely to contact an undercover agent than a real brother "  Abdin  told the undercover agent. "That is why I carry guns in my house  in my car and even I used to secretly take to school. It is very humiliating to be captured."
According to an FBI statement released after  Abdin 's indictment   he  told the agent that if  he  did get to torture an American hostage   he  wanted  his  face shown on video  saying  "I want to be the one to send the message because they know who I am."
 Abdin  also sent a video of  himself  pledging  his  allegiance to the Islamic State in Arabic and told them  he  could do whatever was needed  according to the sworn statement. The FBI said  he  also practiced shooting several different guns during the first three months of 2017.
The FBI said  Abdin  knew agents would learn of  his  purchase and travel plans  and so tried to hide  his  tracks by contacting authorities to tell them  he  bought guns for hunting and would be traveling to the Middle East on a vacation.  He  also asked authorities for a meeting  where  he  told them  he  no longer held the extreme beliefs that led to  his  first arrest.
