(NBC) Warren Christopher Clark, a Texas man recently captured with ISIS fighters in Syria, has been brought back to the U.S. by law enforcement and faces charges of aiding ISIS.
Clark was captured by the Syrian Democratic Forces, a largely Kurdish militia, who transferred him to U.S. custody this week. He was escorted back to Houston by law enforcement and faces a charge of attempting to provide material support to ISIS.
He arrived in Texas Thursday, and his indictment was unsealed Friday morning after his initial appearance in federal court in Houston. The charge of material support carries a possible penalty of up to 20 years in federal prison and a maximum $250,000 fine.
