The 2025 Assembly Joint Resolution 26 honors the life and public service of Senator Timothy Francis Cullen, who was born on February 25, 1944, in Janesville, Wisconsin, and passed away on December 23, 2024. The resolution highlights Cullen's extensive career in public service, beginning with his work as a social studies teacher and ombudsman for U.S. Representative Les Aspin, followed by his election to the Wisconsin State Senate, where he served from 1975 to 1987 and again from 2011 to 2015. During his tenure, Cullen was known for his bipartisan approach, serving as Senate Majority Leader and advocating for policies that improved the lives of Wisconsinites, including consumer protections, housing initiatives, and labor rights.

Cullen's commitment to community service extended beyond his legislative work; he was involved in various organizations and initiatives aimed at fostering leadership and diversity in education. He authored several books and founded the Tim Cullen Government Institute to engage young people in government. The resolution concludes by recognizing Cullen's legacy as a dedicated public servant, husband, father, and mentor, and expresses condolences to his family, friends, and all who were impacted by his work.
