The late William Cheptumo, Baringo’s second Senator, leaves behind an enduring legacy that will be cherished by the people of Baringo and the nation. His commitment to public service spanned over a decade, during which he significantly impacted the lives of his constituents and the legislative landscape of Kenya.

Cheptumo's political journey began in 2008 when he was elected as the Member of Parliament for Baringo North Constituency. Over the next 14 years, he became a familiar face in the halls of power, advocating tirelessly for the needs and concerns of his community.

His ability to connect with the people was evident in his re-election and the trust they placed in him. His transition to the Senate in 2022 was a testament to his dedication and popularity, as he won the seat under the United Democratic Alliance party, defeating prominent opponents, including KANU national chairman Gideon Moi.

Tragically, Cheptumo's service was cut short when he passed away on February 16, 2025, at Nairobi Hospital after battling an undisclosed illness.

His leadership in this committee was marked by a commitment to ensuring that the interests of Baringo County were represented at the national level.

President William Ruto and Senate Speaker Amason Kingi both praised Cheptumo for his hard work and dedication, noting his ability to articulate the concerns of his people with clarity and passion.

During his tenure in the 11th Parliament, Cheptumo was active in various committees, including the Committee on Delegated Legislation, where he served as Chairperson, and the Departmental Committee on Justice and Legal Affairs.

His involvement in these committees underscored his legal expertise and commitment to justice, stemming from his background as a legal officer. Before entering politics, Cheptumo worked at the Industrial and Commercial Development Corporation and the Central Bank of Kenya, where he honed his legal skills. He also founded Cheptumo and Company Advocates, further establishing his credentials in the legal field.

In addition to his legal career, Cheptumo served as an executive in the Ministry of Justice and Constitutional Affairs from 2008 to 2013. This experience provided him with a unique perspective on the intricacies of governance and the importance of legal frameworks in promoting justice and equality.

William Cheptumo's legacy is one of resilience, dedication, and integrity. His contributions to Baringo County and the nation will not be forgotten. He will be remembered as a leader who championed the rights of his people, fought for justice, and worked tirelessly to transform the lives of those he represented.
