Legislative service
Diegnan's political career began when he was elected to the New Jersey General Assembly in 2001, representing the 18th Legislative District. He succeeded Barbara Buono, who had moved on to the New Jersey Senate. Over the course of his legislative career, Diegnan was re-elected for a total of eight terms, serving in the Assembly until 2016. His leadership roles included serving as Deputy Speaker from 2008 to 2016 and as Parliamentarian from 2005 to 2016. He also chaired the Education Committee and was a member of the Regulated Professions and Consumer Affairs Committees.
In 2016, Diegnan transitioned to the New Jersey Senate after being appointed to fill the vacancy left by Peter J. Barnes III, who had been appointed to a judgeship. His appointment was made by local Democratic committee members, and he was sworn into office shortly thereafter. Diegnan subsequently won election to complete the remainder of the term in November 2016. His tenure in the Senate continued his focus on legislative issues pertinent to his district and the state.
During the 2024–2025 Legislative Session, Diegnan was assigned to serve on the Transportation Committee as chair and the Budget and Appropriations Committee. These committee roles reflect his ongoing involvement in key areas of state governance and policy-making.
Policy focus and district

In 2011, Diegnan sponsored Assembly Bill 3852, which sought to require voter approval for the establishment of new charter schools within a district. This legislation was designed to give local communities a voice in the decision-making process regarding charter schools, which had previously been authorized by the Commissioner of the New Jersey Department of Education without community input.

The bill passed in the Assembly, indicating support for his approach to educational governance.
