Texas Republican leaders are pushing back on the Biden administration’s new rules that bar schools from discriminating based on sexual orientation or gender identity.

On Monday, Gov. Greg Abbott said he would direct the state’s education agency to disregard the new rules, calling them a “ham-handed effort to impose a leftist belief.”

Attorney General Ken Paxton sued to block the policy, arguing that the U.S. Department of Education exceeded its authority and wrote an “arbitrary and capricious” rule that expands Title IX, a 1972 anti-discrimination law originally passed to protect women’s rights.
