Texasâ divisive bill restricting how students learn about current events, history, and racism passed by Senate Greg Abbott speaking at the WTTC Global Summit 2016, World Travel and Tourism Council Greg Abbott consulted an infamous climate change denier before Texasâ energy debacle: reporter After hours of passionate debate about how Texas teachers can instruct school children about America's history of subjugating people of color, the state Senate early Saturday morning advanced a new version of a controversial bill aimed at banning critical race theory in public and open-enrollment charter schools. Sen. Bryan Hughes, R-Mineola, introduced a reworked version of House Bill 3979 that also requires the State Board of Education to develop new state standards for civics education with a corresponding teacher training program to start in the 2022-23 school year. The Senate approved the bill in an 18-13 vote over opposition from educators, school advocacy groups and senators of color who worry it limits necessary conversation about the roles race and racism play in U.S. history.
