JD Vance has written a new book in which he discusses his journey to Catholicism and walks back a previous comment about "childless cat ladies", which he now calls "boneheaded" or "one of the dumbest things I ever said". The book also touches on other topics, including the pope and Vance's views on faith and social issues. Vance's comments and the book's themes have been reported on by various outlets, with at least one publication defending the group he previously criticized.
