MacKenzie Scott gave $122.6 million to Big Brothers Big Sisters of America, the national youth-mentoring charity announced on Tuesday.
The gift is the latest of several the billionaire writer has given to large national nonprofits that carry out their missions through local chapters in neighborhoods throughout the country.
With this latest donation, Scott has contributed a total of nearly $12.5 billion since 2020 to at least 1,253 nonprofits, many of which aim to help low-income and underserved populations.
This year, Scott's donations include millions to Habitat for Humanity and Communities in Schools.
Her latest gift to Big Brothers Big Sisters of America follows three other nine-figure donations she gave to large national charities with local affiliates in March.
