This is the second Texas university system sued over teaching restrictions in recent weeks. The university system bars professors from "advocating" race or gender ideology or topics related to sexual orientation or gender identity. The American Association of University Professors brought the lawsuit alongside four professors: Texas A&M professors Leonard Bright, Vanita Reddy and Landon Sadler and Tarleton State University professor Aaron George. Chris Bryan, a spokesperson for the Texas A&M University System, did not immediately respond to a request for comment on Tuesday. It is the second Texas university system to face a lawsuit in recent weeks over academic restrictions.
