State representative Austin Davis (D-Allegheny) announced his resignation from the Pennsylvania House of Representatives in a letter to colleagues on Wednesday.

The resignation will take effect immediately, so Davis can focus on his new role as the state’s lieutenant governor and assist in the transition to the administration of Gov. Josh Shapiro.

“It has been the honor of a lifetime to serve in the state House of Representatives and to be the voice of my community in Harrisburg,” Davis said in a press release. “If you had told me as a 16-year-old teen, driven to my first city council meeting to protest gun violence that had reached my own block, that I would have the privilege to represent my hometown and neighboring communities in our state Capitol, and the opportunity to take those issues head on and improve lives, I wouldn’t have believed it.”

Davis, 33, who represented the Mon Valley, listed his highlights as working to create and expand access to the state’s insurance marketplace, Pennie; working with his fellow Democrats and Republicans to deliver historic state funding for local schools; support local workforce development initiatives; and helping promote the revitalization and redevelopment of the Mon Valley.

“This is a very bittersweet moment for me,” Davis said. “While I am proud of our accomplishments in the House and will miss working with my colleagues there, I am also excited and looking forward to working with Gov. Shapiro to continue to move our commonwealth forward.”
