Mr. Zuckerberg is setting up a foundation with $100 million of Facebook stock to be used to improve education in America, with the primary goal of helping Newark.

The donation has the potential to be matched by another $100 million that Newark's mayor, Cory Booker, has been working on raising from private foundations and others. [...]

The $200 million that could be raised would amount to over 20% of Newark's budget of $940 million.
