Former Fox News Host's Books Removed From Florida Schools

The Florida Freedom to Read Project recently obtained a list of books that have been temporarily removed from libraries in the Escambia County Public School District, which included encyclopedias, The Guinness Book of World Records and two books from conservative pundit O'Reilly: Killing Jesus: A History, and Killing Reagan: The Violent Assault That Changed a Presidency.

In a further statement to the Pensacola News Journal, a district spokesperson clarified that the books included on the list obtained by the Florida Freedom to Read Project "have not been banned or removed from the school district; rather, they have simply been pulled for further review to ensure compliance with the new legislation."

According the Wikipedia page of Killing Jesus:

The second chapter describes the life of the Roman general and dictator Julius Caesar, his conquests, his seduction by the Egyptian Ptolemaic queen Cleopatra, and his eventual assassination.

Chapter Seven describes the alleged debaucheries of the Roman emperor Tiberius at Capri, described by the Roman historian Seutonius, accepting all of them as historical.

What are these debaucheries? According to the Wikipedia page of Tiberus:

While Tiberius was in Capri, rumours abounded as to what exactly he was doing there. Suetonius records the rumours of lurid tales of sexual perversity, including graphic depictions of child molestation, cruelty, and most of all his paranoia. While heavily sensationalised, Suetonius' stories at least paint a picture of how Tiberius was perceived by the Roman senatorial class, and what his impact on the Principate was during his 23 years of rule.

As for Killing Regan, the Wikipedia page doesn't provide an indepth summary like Killing Jesus. However, it does say this:

In an op-ed published in National Review, she further stated, "Why the authors want to present this distorted 'witch and wimp' view of Nancy [Reagan] and the 40th president is puzzling, especially since an alternative view of the effect of Reagan's near-death experience is so readily available."

My guess there's a couple of chapters of Throat GOAT Nancy Regan giving someone head.
