RALEIGH, N.C. (AP) — North Carolina Republicans in the General Assembly have fallen short trying to overturn Democratic Gov. Roy Cooper’s vetoes on teacher pay and the budget during a one-day session. The Senate failed on Tuesday to override Cooper’s veto of a measure that would have enacted pay raises for teachers, teacher assistants and other staff at levels contained in the larger two-year budget Cooper also vetoed last June. A budget stalemate has dragged on ever since, save for several “mini-budgets” that have been approved. Now the impasse will extend at least until late April, when the General Assembly is next scheduled to meet.
