WASHINGTON (AP) – Joe Biden is releasing his presidential financial disclosure, which shows that the former vice president earned millions of dollars, including more than $2.7 million for book deals and speaking engagements over the past year and a half. During a four-decade political career, Biden brought home little more than his government salary. But since leaving the White House in January 2017, Biden has become a millionaire. His newfound wealth stems from a lucrative publishing deal, publicity tours and other speaking engagements. Biden’s first book, an account of his son Beau’s death from cancer, briefly topped bestseller lists in 2017. Biden also earned $540,000 as a professor and namesake of the University of Pennsylvania’s Penn Biden Center for Diplomacy and Global Engagement. He is now seeking the 2020 Democratic nomination for president.
