An Oklahoma House committee on Monday approved a bill taking aim at the new AP U.S. History framework, which conservatives have decried as unpatriotic and negative, the Tulsa World reported.

State Rep. Dan Fisher (R) introduced a bill at the beginning of the month that keeps the state from funding AP U.S. History unless the College Board changes the curriculum. The bill also orders the state Department of Education to establish a U.S. History program that would replace the AP course.

Since the College Board released a new course framework for U.S. history in October 2012, conservative backlash against the course has grown significantly. The Republican National Committee condemned the course and its “consistently negative view of American history” in August. Numerous states and school districts have now taken action to denounce the exam.

Fisher said Monday that the AP U.S. History course emphasizes “what is bad about America” and complained that the framework eliminated the concept of “American exceptionalism,” according to the Tulsa World.

The House Common Education Committee voted for the bill 11-4, with all Republicans voting for the legislation and all Democrats voting against it.

During the hearing on the bill, state lawmakers also questioned the legality of all AP courses, comparing them to Common Core, which Oklahoma has repealed. According to the Tulsa World, lawmakers were concerned that College Board courses could be seen as an effort to create a national curriculum.

Rep. Sally Kern (R) said that she asked the state attorney general to review whether AP courses violate the legislation that repealed Common Core.
