Qatanani's trial in federal court in Newark entered its second day on Friday.
He's facing deportation for not mentioning a 1993 conviction in Israel on his U.S. citizenship application. The Israeli military charged Qatanani with being a member of the militant Hamas organization.
Qatanani claims he was convicted without his knowledge after three months of detention that included physical and mental abuse. He has said he did not become aware of the conviction until last fall.
