Amazon founder and CEO Jeff Bezos is donating $100 million to food banks across the U.S. so they can feed needy Americans as the novel coronavirus cripples the economy.

“Even in ordinary times, food insecurity in American households is an important problem, and unfortunately COVID-19 is amplifying that stress significantly,” Bezos said on Instagram Thursday. “Millions of Americans are turning to food banks during this time.”

The donation will go to Feeding America, a Chicago-based network of more than 200 food banks that feed 46 million people. Forbes ranked Feeding America the second-largest U.S. charity by revenue. The nonprofit generated $2.9 billion in revenue in 2019, most of which went toward sending food to pantries, according to a 2019 financial report.
