The handling of Ahmed Abu Khatallah is likely to unfold according to an established administration script followed in other terrorism cases: he’ll be interrogated for several days, likely aboard a U.S. ship, and then brought to the United States for a trial in a civilian court.

“The only question in my mind is how slowly they’ll be moving that ship,” said New York University law professor Ryan Goodman.

Those plans are already drawing fire from some GOP critics.

“Ahmed Abu Khattala should be held at Guantanamo as a potential enemy combatant,” Sen. Lindsey Graham (R-S.C.) wrote on Twitter Tuesday. “Holding Khattala on a ship shows the haphazard approach which comes from not having rational detention & interrogation policies.”

Sen. Marco Rubio (R-Fla.) also said the administration should “immediately” transfer Khatalla to Gitmo. “In order to locate all individuals associated with the attacks that led to the deaths of four Americans, we need intelligence,” he said in a statement. “That intelligence is often obtained through an interrogation process.”
