(CNN)Texas Gov. Greg Abbott, a Republican, called on the state's school boards to remove books he described as "pornography," a move that comes after at least two state lawmakers have asked officials to investigate books in schools.

Abbot's letter, sent to the Texas Association of School Boards on Monday, did not cite a specific book that contains what he described as "pornography." Last week, Texas Republican lawmaker, Jeff Cason, released a statement calling on the state's Attorney General to investigate books he also described as "pornography." In his statement, he singled out the graphic novel "Gender Queer" by Maia Kobabe.

This is not the first time Kobabe's book and other LGBTQ books are targeted by politicians and community members.

(Personally, I have found that books generally describe heterosexual sex a lot more graphically and in much more detail than the LGBTQ+ books.)
