Matt Wilson writes: “Mission Consolidated Independent School District (CISD) in the Rio Grande Valley of Texas says it won’t remove or review 676 books the school system’s former superintendent committed to purging earlier this summer. In May Mission CISD, like other Rio Grande Valley districts, received an email from local representatives of a conservative advocacy group. Former Superintendent Carol G. Perez unequivocally agreed to remove all the books on the group’s list minutes after receiving their email. Perez, however, left her position as the district’s chief last month and Mission’s new superintendent says no books were removed or are going to be removed based on the group’s request.”
