Between 2020 and 2022, the number of book titles that have been banned in U.S. libraries and schools spiked more than 1,100%, to more than 2,500, while activists in 37 states have challenged school districts for offering non-fiction and fiction books that discuss race and racism, slavery, sex and gender identity. Correspondent Martha Teichner talks with opposing forces on the reading battlefield today, from the founders of the activist group Moms for Liberty, to library officials, a teacher removed from her classroom for giving her students access to banned books, and cartoonist Art Spiegelman, whose Holocaust-themed graphic novel "Maus" has been targeted by book banners. @Brooklyn-Public-Library #bannedbooks #censorship #reading "CBS Sunday Morning" features stories on the arts, music, nature, entertainment, sports, history, science and Americana, and highlights unique human accomplishments and achievements.
