MAKATI CITY, Philippines--Rodolfo Lozada Jr., the key witness in the Senate investigation of the national broadband network (NBN) controversy, says he is not calling for the resignation of President Gloria Macapagal-Arroyo when asked by a law student. Lozada stresses that his work ends when he divulges the controversies surrounding the NBN deal and it is up to the people to decide what to do next. Lozada also says that before the President can be held liable, people should wait for Romulo Neri's side of the story. Video taken by INQUIRER.net multimedia editorial assistant Abigail Kwok.
