Joseph Sempolinski is an American politician who served as a U.S. Representative for New York's 23rd congressional district from 2022 to 2023. A member of the Republican Party, Sempolinski was elected during a special election held in August 2022, following the resignation of his predecessor. His tenure in the U.S. House of Representatives was marked by his involvement in key committees and a commitment to his constituents. After concluding his term in January 2023, he announced plans to run for the New York State Assembly in 2024.
Early life and career
Joseph Sempolinski was born on February 10, 1983, in Elmira, New York. He grew up in the region and completed his secondary education at Corning-Painted Post West High School, located in Painted Post, New York. Following high school, he pursued higher education, earning a Bachelor of Arts degree from Georgetown University, a prestigious institution known for its rigorous academic programs and notable alumni. Sempolinski furthered his education at Yale University, where he obtained both a Master of Arts and a Master of Philosophy. His academic background provided a strong foundation for his future endeavors in public service and politics.
Sempolinski began his professional career in the political arena in 2010 when he joined the office of Congressman Tom Reed. Over the next five years, he held various roles, including that of District Director. This experience allowed him to gain valuable insights into the legislative process and the workings of Congress. His involvement in Reed's office helped him build a network within the Republican Party and develop a deeper understanding of the needs and concerns of constituents in New York.
In addition to his work with Congressman Reed, Sempolinski took on a leadership role within the Republican Party at the local level. He served as the Chairman of the Steuben County Republican Committee, where he was responsible for organizing party activities and supporting Republican candidates in local elections. His commitment to the party and his community positioned him as a prominent figure within the local political landscape.
Before his congressional run, Sempolinski served as Chief of Staff for New York State Assemblyman Joseph Giglio. In this capacity, he was involved in various legislative initiatives and constituent services, further solidifying his reputation as a dedicated public servant. His experience in both state and federal politics equipped him with the skills necessary to navigate the complexities of governance.
House tenure
Sempolinski's journey to the U.S. House of Representatives began with the resignation of Congressman Tom Reed on May 10, 2022. Reed had announced that he would not seek re-election, creating a vacancy in New York's 23rd congressional district. The district's boundaries were set to be redrawn following the 2020 United States Census, which added another layer of complexity to the special election process.
As the special election approached, two prominent Republican candidates initially emerged, but both ultimately decided not to pursue the seat due to residing outside the newly drawn district boundaries. In light of this situation, the Republican county chairmen from the district selected Sempolinski as their candidate for the special election. His selection was indicative of his standing within the local party and his perceived ability to represent the interests of the constituents.
On August 23, 2022, Sempolinski faced Democratic nominee Max Della Pia in the special election. He successfully won the election, securing approximately 53% of the vote against Della Pia's 47%. Sempolinski's victory was characterized by strong support across most of the district, as he won in ten out of the eleven counties that comprised the district. However, Della Pia garnered significant support in Tompkins County, highlighting the diverse political landscape within the district.
Upon being sworn in on September 13, 2022, Sempolinski immediately began his work in Congress. He pledged not to seek re-election in the upcoming November general election, which shaped his approach to his responsibilities during his time in office. His decision not to run for a full term allowed him to focus on fulfilling his commitments to his constituents without the pressures of a re-election campaign.
Legislative focus and committees
During his brief tenure in the U.S. House of Representatives, Sempolinski was assigned to two key committees: the United States House Committee on the Budget and the United States House Committee on Education and Labor. These committee assignments reflected his interests and areas of focus within the legislative process.
As a member of the House Committee on the Budget, Sempolinski participated in discussions and decisions regarding federal budgetary matters. This committee plays a crucial role in shaping fiscal policy and determining funding priorities for various government programs and initiatives. His involvement in budgetary discussions allowed him to advocate for the needs of his constituents and the broader community in New York.
In addition to his work on budgetary issues, Sempolinski served on the House Committee on Education and Labor. This committee oversees a wide range of topics, including education policy, labor relations, and workforce development. Sempolinski's participation in this committee provided him with the opportunity to engage in discussions about important issues affecting education and labor in his district and beyond.
Following the conclusion of his term in the U.S. House of Representatives on January 3, 2023, Sempolinski announced his intention to run for the New York State Assembly in the 148th district in 2024. This decision marked a continuation of his political career and a desire to serve at the state level. His previous experience as Chief of Staff for Assemblyman Joseph Giglio positioned him well for this new challenge, as he sought to succeed Giglio in representing the interests of constituents in the state assembly.
In summary, Joseph Sempolinski's political career has been characterized by a commitment to public service, a strong foundation in education, and a focus on the needs of his constituents. His tenure in the U.S. House of Representatives, though brief, allowed him to engage in significant legislative discussions and contribute to the governance of his district. As he transitions to a new role in the New York State Assembly, he continues to build upon his experience and dedication to serving the people of New York.
