All preparations have been finalised for a decisive two-day impeachment trial that will determine whether Nyamira Governor Amos Kimwomi Nyaribo remains in office. The Senate will on Wednesday 3 and Thursday 4 December 2025 sit as a trial court to hear charges brought against the Governor by the Nyamira County Assembly, in proceedings expected to draw national attention.
The hearings will open with the formal reading of charges, after which Governor Nyaribo will be invited to enter a plea. The County Assembly, which initiated the impeachment, will then present its case first, tabling documents, calling witnesses and arguing why the Governor should be removed.
Once the Assembly concludes its submissions, Nyaribo’s defence team will take the floor to challenge the accusations, cross-examine witnesses and present evidence aimed at clearing the Governor of wrongdoing.
The process will culminate on Thursday with a crucial vote by Senators, who will decide—by county delegations—whether to uphold the impeachment or acquit the Governor.
By a letter dated 25 November 2025 and received by the Senate the following day, the Speaker of the Nyamira County Assembly formally notified the Speaker of the Senate of the Assembly’s approval of the impeachment Motion and forwarded all supporting evidence. The Assembly impeached Governor Nyaribo on two broad grounds: gross violation of the Constitution and other laws, and abuse of office.
On the first ground, the Assembly accuses the Governor of engaging in, endorsing and supporting the unlawful and unconstitutional “Bunge Mashinani” initiative. He is also alleged to have given illegal assent to the Nyamira County Supplementary Appropriation Bill of 2024, and to have made an unlawful appointment of Dr Peris Nyaboke Oroko, also known as Peris Mongare, as a County Executive Committee Member.
The Assembly further claims that he illegally appointed members of the Nyamira and Keroka Municipal Boards, unlawfully constituted a selection panel for the County Public Service Board and failed to appoint the Board’s chairperson, secretary and members.
Additionally, it accuses him of failing to deliver the State of the County Address and the mandatory Annual Reports, and of disregarding court orders relating to the appointment of Mr Clive Ogwora to the County Executive Committee.
On the charge of abuse of office, the Governor is accused of conducting staff recruitment without budgetary provision, influencing irregular appointments of senior human resource officers and enriching himself through irregular salary arrears.
According to the Assembly, his administration presided over a payroll fraud syndicate that led to the loss of public funds. It further alleges that he made dual appointments outside the lawful establishment, usurped the powers of the Auditor-General and the County Public Service Board, and unlawfully suspended the CPSB Secretary.
An attempt by Majority Leader Aaron Cheruiyot to establish an 11-member select committee to handle the impeachment collapsed after failing to secure a seconder. The Speaker therefore directed that the matter proceed to full plenary hearings, where all Senators will participate directly in examining the charges.
The Clerk of the Senate was instructed to issue appearances invitations to all parties and to receive their submissions by Monday, 1 December at 5 p.m. All documents, including the plenary hearing programme, were to be circulated to Senators by close of business on Tuesday, 2 December.
As the Senate prepares to sit in judgment, the future of Governor Nyaribo now rests on the evidence laid before the House—and the verdict Senators will deliver at the close of the historic trial.
