Vanity Fair contributing writer Chris Whipple spent six months examining JD Vance's years at Yale Law School, including the influence of professor Amy Chua and previously unreported contacts in which Whipple says Vance offered Hillary Clinton's 2016 campaign advice on defeating Donald Trump. Whipple is on Bloomberg This Weekend and discusses how his reporting traces Vance's evolution from a prominent Trump critic to Trump's vice president, while examining the relationships and experiences that helped shape his political career.
