It's Friday, which means it's time for our weekly "Tough Questions" segment with PEN America CEO Suzanne Nossel, author of the forthcoming book Dare to Speak: Defending Free Speech for All. As we near the book's publication date, we discuss how the social platforms are dealing with the crisis in Hong Kong; we dissect the U.S. government's threat to ban the ever-popular Tik Tok; and we delve into the controversy surrounding a letter in Harper's Magazine about free speech.
