Joyce, John

John Patrick Joyce represents Pennsylvania's 13th congressional district, a largely rural area spanning south-central Pennsylvania including Altoona, Chambersburg, and Gettysburg. Elected in 2019 to succeed retiring congressman Bill Shuster, Joyce brings a background in dermatology to his legislative work. As chair of the Oversight and Investigations subcommittee within the House Energy and Commerce Committee, he holds significant power to launch investigations into federal agencies, schedule hearings, and direct the subcommittee's priorities—though the full committee's agenda remains controlled by the majority party leadership.

Joyce's medical background informs his legislative focus on healthcare policy. He has sponsored bills addressing diabetes foot health access, broadband expansion in rural areas, and health technology investment, reflecting both his district's needs and his professional expertise. His work on the Energy and Commerce Committee positions him at the center of major policy debates spanning energy, telecommunications, healthcare, and environmental regulation. As an oversight subcommittee chair, he plays a key role in congressional accountability efforts, though his influence is constrained by the broader committee structure and majority party dynamics.
