Biden and Wife Made More Than $15M After Leaving Office Reuters WASHINGTON - Former U.S. Vice President Joe Biden and his wife, Jill, earned more than $15 million in the two years after Biden left government in early 2017, according to tax records released by his campaign on Tuesday. The majority of their income came from speaking engagements and payments for two books written by Biden, a top contender for the 2020 Democratic presidential nomination. The former U.S. senator from Delaware served as Barack Obama's vice president for eight years, leaving office in January 2017 after the election of Republican President Donald Trump. According to federal and state tax returns, the Bidens earned about $11 million in 2017 and $4.58 million in 2018. About $13.2 million of that was attributable to book payments. Biden earned more than $775,000 in salary as a professor at the University of Pennsylvania in 2017 and 2018. The Biden campaign released a financial disclosure form mandated for presidential candidates, which provided details of his speaking engagements and book events from Jan. 1, 2018, to May 31, 2019. .
