 Starting this fall, many won't pay tuition after a $1 billion gift from Michael Bloomberg's philanthropic organization. The donation will cover full tuition for students from families earning less than $300,000, and that means nearly two-thirds of the students will be eligible. Bloomberg, a 1964 graduate of the school, donated heavily to the school in the past, including $1.8 billion in 2018 for undergraduate financial aid. I'm Janine Herbst, NPR News.
