"A deeply personal decision": Shapiro expresses support for Harris-Walz ticket

• "Over the next 90 days, I look forward to traveling all across the Commonwealth to unite Pennsylvania behind Kamala Harris' campaign to defeat Donald Trump," Shapiro wrote.

What he's saying: "The running mate decision was a deeply personal decision for the vice president — and it was also a deeply personal decision for me," Shapiro wrote.

• "Pennsylvanians elected me to a four-year term as their governor, and my work here is far from finished."

Between the lines: Shapiro said he spoke with Harris on Sunday "about her vision for the role and the campaign ahead."

• He was part of the vetting process for nearly two weeks, he said.

Zoom out: Shapiro has been governor of Pennsylvania since January 2023, and he has built a reputation as a strong communicator and crisis manager.

• "I'm excited to continue working to protect and advance real freedom, deliver good schools, safe communities and economic opportunity," he wrote.
