US Vice President JD Vance has written a book about his journey to Catholicism, titled "Communion", which discusses his conversion and mentions various influences and individuals, including Ayn Rand and Peter Thiel. The book also reportedly touches on his political views and a meeting at the Vatican that he found unsettling. Some outlets have noted that Vance addresses past controversial comments in the book, including his remark about "childless cat ladies", which he now calls "one of the dumbest things" he ever said.
