Twenty-six-year-old Mahmoud Elhassan of Woodbridge, Virginia, was arrested last year after he drove Joseph Farrokh to the Richmond airport, where he planned to begin a trip to join the Islamic State in Syria.
Prosecutors say Elhassan, who started a prayer table outside the Verizon Center in Washington seeking to proselytise others to Islam, offered himself online as a "sleeper cell" to overseas radicals.
The government sought a term closer to the 28-year maximum at a hearing Friday in Alexandria, Virginia.
