A couple Portland lawmakers are backing a proposal to overturn the "proof of legal residency" requirement to get Oregon driver's licenses. They say it's about public safety. Some Portland lawmakers say the requirement to show a birth certificate or passport often makes it hard for low-income Oregonians and seniors to get licenses. But also it can make it difficult for seasonal farm workers to do their jobs. Alberto Moreno with Oregon Latino Agenda for Action says: “That group of workers alone contribute over $4.3 billion in annual agricultural economic activity.” Opponents says the driver's license is a valuable piece of I.D. that should not be handed out to people who cannot prove their right to reside in the state. Public hearings have not been scheduled.
