The roster carries this entry as 'Khalid Mustapha'; the confirmed sitting senator is Ibrahim Khalid Mustapha (also rendered 'Khalid Ibrahim Mustapha'). He was elected in February 2023 on a Peoples Democratic Party (PDP) ticket, defeating incumbent APC senator Suleiman Abdu Kwari with 250,026 votes against 190,008, and assumed office on 29 May 2023. He subsequently resigned his PDP membership in a letter dated 27 March 2026 and joined the African Democratic Congress (ADC), with the defection read on the Senate floor in May 2026 — a mid-term party switch his successor's 2027 ADC primary entry (83,070 votes, uncontested) confirms. On legislative output, two establishment bills are on record in his name: SB 214 (Federal College of Crop Science and Food Technology, Lere, introduced November 2023) and SB 170 (Federal College of Education Technical, Saminaka, introduced March 2024); both target Kaduna North's educational infrastructure but no enactment or passage to third reading has been confirmed in open sources. He holds committee positions as vice chairman on the Senate Committee on Ethics, Privileges and Public Petitions and, after a post-reshuffle assignment, on the National Atomic and Nuclear Energy Committee. He co-sponsored a motion on banning textile imports to revive local industry. No independently verified constituency project delivery — zonal interventions, empowerment distributions, or physical infrastructure — has been located in open-access sources for the Kaduna North district. A Daily Trust commentary one year into his tenure noted that he had performed below expectations relative to his two Kaduna State Senate colleagues. No EFCC, ICPC, or court proceedings have been located in connection with his conduct in office.
