Senator Yahaya Abubakar Abdullahi has served Kebbi North continuously since 2015, ascending to Senate Majority Leader in the 9th Assembly (June 2019 to June 2022) under Senate President Ahmad Lawan. His legislative record as Majority Leader includes floor leadership on major bills including the Electoral Act (Amendment) Bill 2021 and motions on the Finance Act. In the 10th Assembly he chaired the Committee on National Planning and Economic Affairs before being elevated in December 2025 to Chairman of the Senate Committee on National Security and Intelligence. A dual-party defection record -- APC to PDP in June 2022 after a disputed governorship primary, then PDP back to APC in May 2025 ahead of the 2027 elections -- is the most documented feature of his integrity record. Independently verified constituency delivery data for Kebbi North is thin: no published BudgIT or Tracka audit of his zonal intervention projects has been located. His academic and civil service background (permanent secretary, associate professor) gives him unusual policy depth, but specific documented legislative outputs from his own bill portfolio across all three terms remain incompletely catalogued in open public sources.
