Self-proclaimed “Middle Class Joe” Biden has made millions since leaving the White House.

Biden and his wife Jill have earned a combined $15 million in the two years since the end of the Obama Administration, according to tax returns and financial documents released by his presidential campaign.

Much of their income was generated through book deals and speaking engagements.

NPR reports:

The documents show Biden has earned far more than the rest of the 2020 presidential field, with the likely exception of billionaire Tom Steyer, who entered the race Tuesday.

The Bidens’ adjusted gross income for 2018 was $4.5 million. It was even higher — $11 million – in 2017. They have paid a federal tax rate of just over 33% each year.

By comparison, Vermont. Sen Bernie Sanders earned $561,293 last year, California Sen. Kamala Harris reported $1,884,319. Massachusetts Sen. Elizabeth Warren took in $846,394, and South Bend, Ind., Mayor Pete Buttigieg reported $152,643.
