RALEIGH, N.C. (AP) - North Carolina Gov. Beverly Perdue has vetoed the state budget proposal becoming the first governor to ever veto a spending plan passed by the Legislature. The Democrat rejected the nearly $20 billion budget plan Sunday, saying it moves North Carolina backward, particularly in public education. She also said the plan will hurt the environment and cut health care for the needy. The bill can still become law. Republicans in the House and Senate say they have enough votes to override her veto. Five House Democrats joined GOP lawmakers when the budget bill got final approval last weekend. North Carolina governors have vetoed 15 bills since receiving the power in 1997, but one has never rejected the budget plan.
