Huffpost reported the story first.
Governor Shapiro and his family were asleep at the mansion and woke up to bangs on their door only to discover the fire. The police were first and the fire department got them out safely.
The police say that they're prepared to say that it's a case of arson immediately.
What's especially concerning is that it happened on the first night of Passover, and of course, Shapiro is Jewish.
