The officials said he had been previously held by the US-backed Syrian Democratic Forces, a group of Kurdish-led anti-ISIS fighters that are currently holding over 2,000 foreign ISIS fighters from over 50 countries.
The US military helped facilitate the transfer.
“The Department of Defense assisted in the movement of a US national from Syria to the United States. He was previously held by Syrian Democratic Forces as a suspected member of ISIS,” a Pentagon spokesperson later confirmed to CNN.
“He was transferred to the US for prosecution. As a matter of policy, DOD does not discuss matters of litigation; so for further details, please contact the Department of Justice,” the spokesperson added.
