The additional legal firepower comes about five months before a December jury trial is set to begin in federal district court.It’s not clear why the district brought on lawyers from the Heritage Foundation and Alliance Defending Freedom at this point in the case. A statement provided by a district spokesman said that Alliance Defending Freedom has a 20-win record before the U.S. Supreme Court. It also said that the district is the first client of Heritage’s new Legal Action Center, which was created for cases like the library book lawsuit. “The District has assembled this legal team to mount a vigorous, well-resourced defense of its policies on the merits,” the statement said. The three lawyers join the book removal case at a tumultuous time for the district. In May, the previous superintendent was forced out and a new superintendent was hired. The district is also facing a financial crisis caused by overspending, leading to staff layoffs and other cuts this summer. The district has been soliciting donations for its legal defense in the book removal case since last summer. In May, district leaders took steps to create Friends of Elizabeth Schools, a group intended to fundraise for legal costs. The Elizabeth district spokesperson said he did not have information about how much the district has spent on the library book lawsuit so far or whether Heritage and Alliance Defending Freedom attorneys will charge the district for their work. The additional lawyers will join at least two other firms already representing Elizabeth in the case. The controversy over the books, which are back on school library shelves while the case is pending, began in the fall of 2024 when the district in conservative-leaning Elbert County decided to pull 19 titles from school libraries because of content school board members deemed not age appropriate, overly graphic, or highly sensitive. One of the books was not actually removed because it had been checked out and was never returned.The removed books are primarily by or about LGBTQ people, people of color, or both. They include “The Bluest Eye” and “Beloved,” both by Toni Morrison; “The Kite Runner,” by Khaled Hosseini; and “It’s Your World — If You Don’t Like It, Change It” by Mikki Halpin. In December 2024, two students, a chapter of the NAACP, and an authors group, all represented by the American Civil Liberties Union of Colorado, sued the Elizabeth district over the book removals. They alleged that the removals violate students’ rights under the U.S. Constitution’s First Amendment to access information and ideas and authors’ rights to communicate those ideas to students.Lawyers for the district rebutted those claims in a 2025 legal filing, saying “a school library’s curation decisions are government speech immune from First Amendment scrutiny.” The Heritage Foundation is a conservative public policy group that produced Project 2025, a playbook for the second Trump administration. The document’s introduction says,“Children suffer the toxic normalization of transgenderism with drag queens and pornography invading their school libraries.” Heritage’s Legal Action Center launched in July and described its goals on social media as defending “free speech, religious liberty, election integrity, parental rights, medical freedom, the right to life, and the constitutional principles that safeguard liberty.” Alliance Defending Freedom is an Arizona-based conservative law firm and legal advocacy group that describes its mission as “grounded in the historic Christian tradition.” Ann Schimke is a senior reporter at Chalkbeat.
