A strike by Oklahoma educators demanding more school funding extended to a 10th day on Wednesday, as the state's Republican leaders warned they planned no further increases after approving $450 million in new revenue to boost teacher pay. Schools in the state's largest metro areas serving hundreds of thousands of students remained closed the day after Republican Governor Mary Fallin signed into law two bills that raised taxes but fell short of the teachers' demand for $150 million above what had already been approved. "The governor and lawmakers keep closing the door on revenue options when Oklahomans are asking for a better path forward," said Alicia Priest, president of the Oklahoma Education Association, the state's largest union for teachers, with about 40,000 members.
