Alito's confirmation hearing was held from January 9 to 13, 2006. Two active-duty members of the Third Circuit, Judge Maryanne Trump Barry and Chief Judge Anthony J. Scirica, testified in Alito's confirmation hearing, as did five senior and retired circuit judges. Alito responded to some 700 questions over 18 hours of testimony. He rejected the use of foreign legal materials in the Constitution, did not state a position on cameras in courtrooms (he had supported them while on the 3rd Circuit), said Congress could choose to outlaw LGBT employment discrimination in the United States if it wished, and told Senator Joe Biden (D-DE) that he endorsed a weak version of the unitary executive theory.
