HARRISBURG, Pa. (AP) —Police said Sunday that officers evacuated Gov. Josh Shapiro and his family from the official governor’s residence after someone set fire to the building.

No one was injured and the fire was extinguished, according to authorities.

The fire broke out overnight on the first night of the Jewish holiday of Passover, which Shapiro and his family had celebrated at the governor’s official residence in the state capital of Harrisburg. State Police said in a statement that, while the investigation was ongoing, they were “prepared to say at this time that this was an act of arson.”

Police gave no other details about the cause.

In a statement, Shapiro, viewed as a potential White House contender for the Democratic Party in 2028, said he and his family woke up at about 2 a.m. to bangs on the door from the Pennsylvania State Police after the fire broke out.

The Harrisburg Bureau of Fire was called to the residence and, while they worked to put out the fire, police evacuated Shapiro and his family from the residence safely, Shapiro said.

“Thank God no one was injured and the fire was extinguished,” Shapiro said in a statement.

State police are leading the investigation. The agency offered a reward of up to $10,000 for information leading to an arrest and conviction.
