A billionaire just made a huge donation to three Pennsylvania children's hospitals.
NASA Administrator Jared Isaacman announced today he is giving $30 million to help expand UPMC Children's Hospital in Pittsburgh, Children's Hospital of Philadelphia and the Guthrie Clinic.
Locally, the donation will help expand the UPMC Children's Heart Institute, which is undergoing an expansion into a new state-of-the-art facility in one location.
It's not clear the size of each individual donation.
Isaacman's net worth is $1.2 billion.
