WASHINGTON — Senior national security officials in the Trump administration are embracing a proposal to transfer to Saudi Arabia an American citizen being held in Iraq as a wartime detainee, according to officials familiar with internal deliberations.

A meeting last week of the National Security Council’s “deputies committee” — the No. 2 leaders of national security departments and agencies — found its members united around a goal of pursuing such a transfer for the detainee, suspected of being a low-level Islamic State fighter, who has been held in military custody as an “enemy combatant” for the past three months, the officials said.

The man, whose name the government has refused to make public, was born in the United States to visiting Saudi parents, the officials said.

A spokesman for the National Security Council declined to comment. The officials spoke on the condition of anonymity to describe the internal deliberations.
