MacKenzie Scotts $26 billion philanthropic legacy came under renewed scrutiny after Elon Musk and Katie Miller criticized the billionaires charitable giving and questioned the causes receiving her money. Miller claimed Scotts donations have largely supported progressive organizations, while Musk previously voiced similar criticism of her philanthropy. Scott, Jeff Bezos ex-wife, has donated billions through Yield Giving since 2020, supporting thousands of nonprofits across education, healthcare, housing, racial equity, climate initiatives and community development.
