A Republican state lawmaker has launched an investigation into Texas school districts over the type of books they have, particularly if they pertain to race or sexuality or "make students feel discomfort."

State Rep. Matt Krause, in his role as chair of the House Committee on General Investigating, notified the Texas Education Agency that he is "initiating an inquiry into Texas school district content," according to an Oct. 25 letter obtained by The Texas Tribune.

Krause's letter provides a 16-page list of about 850 book titles and asks the districts if they have these books, how many copies they have and how much money they spent on the books.

His list of titles includes bestsellers and award winners alike, from the 1967 Pulitzer Prize-winning novel “The Confessions of Nat Turner” by William Styron and “Between the World and Me” by Ta-Nehisi Coates to last year's book club favorites: “Hood Feminism: Notes from the Women that a Movement Forgot” by Mikki Kendall and Isabel Wilkerson's “Caste: The Origins of Our Discontents.”

But race is not the only thing on the committee chair’s list. Other listed books Krause wants school districts to account for are about teen pregnancy, abortion and homosexuality, including “LGBT Families” by Leanne K. Currie-McGhee, “The Letter Q: Queer Writers’ Notes to their Younger Selves” edited by Sarah Moon, and Michael J. Basso’s “The Underground Guide to Teenage Sexuality: An Essential Handbook for Today’s Teens and Parents.”

Krause, a Fort Worth lawmaker and founding member of the House Freedom Caucus, is running for state attorney general against Ken Paxton. Krause declined to comment and no explanation was given as to how these books were chosen.

Krause sent notice of the investigation to Lily Laux, the Texas Education Agency deputy commissioner of school programs, as well as some Texas school superintendents. His letter did not specify which school districts Krause was investigating.
