HARRISBURG, Pa. (AP/WHTM) — Pennsylvania’s high-profile attorney general, Josh Shapiro, officially announced his intention to run for governor the morning of Wednesday, Oct. 13, via Twitter.

Previously on Monday, Oct. 11, a spokesperson with Shapiro confirmed the set announcement with abc27.

The 48-year-old is a self-described progressive who led a nationally prominent investigation into sexual abuse of children by clergy. He further raised his political profile by pushing back against Donald Trump’s effort to overturn his election loss last year.

“Each of us has a responsibility in life to get off the sidelines, get in the game, and do our part to make things better,” Shapiro said in his campaign announcement video.

Shapiro is the only announced Democratic candidate for governor. The Democratic incumbent, Gov. Tom Wolf, is constitutionally barred from running for a third term.

On the opposite side, there are nine Republican candidates in the race with Bill McSwain, a federal prosecutor under former President Donald Trump, being the most recent addition.
