The United Way of Tucson and Southern Arizona received a $10 million donation Tuesday, the largest in the organizationâs nearly 100-year history. The funds will be used to âfight racial and economic disparities, address COVID-19 relief and meet other pressing community needs throughout the region,â according to a news release from the organization. The donation came from MacKenzie Scott, an author, philanthropist and ex-wife of Jeff Bezos, the founder of Amazon. Scott announced the donation Tuesday as part of her effort to give away her vast fortune during her lifetime. She pledged to donate nearly $4.2 billion to 384 organizations that fulfill basic needs during the coronavirus pandemic, such as food banks, or âlong-term systemic inequities that have been deepened by the crisis,â including debt relief and employment training.
