Al-Bakhit said Ayham al-Samaraie, who holds dual U.S. and Iraqi citizenship, arrived on a U.S. plane.
He said Iraq has not demanded al-Samaraie's extradition, and did not give his location.
Al-Samaraie was electricity minister during the Iraqi transitional government set up in 2003, and was imprisoned in August on corruption charges.
