At the Los Angeles Times, "Temecula school board outrage over LGBTQ+ lessons motivates Newsom to rush new textbook law":
Temecula and most of southwestern Riverside County lean Republican, favoring former President Trump in the 2020 election and creating a rift with California’s Democratic state leaders. In December, the school board voted to ban the teaching of critical race theory. On Wednesday, Newsom announced that the state is entering into a contract to secure textbooks for the district in time for the first day of school next month. “The three political activists on the school board have yet again proven they are more interested in breaking the law than doing their jobs of educating students — so the state will do their job for them,” Newsom said in a statement, reiterating his commitment to fining the district. Newsom — a national voice against red state policies — was so inspired to take on Temecula conservatives that he has publicly vowed to hold the school district accountable on the basis of a law that does not yet exist...Laws?
