(Tijuana) -- The trial is underway for a U.S. Marine jailed in Mexico on weapons charges. Sergeant Andrew Tahmooressi was arrested March 31st after he crossed the border near San Ysidro , California with guns and hundreds of rounds of ammunition in his pickup truck. He spent about five hours in court Monday where two Mexican border agents testified. Tahmooressi's lawyer is trying to show those agents violated his civil rights the night he was arrested.
