Radio Presenter Oga Obinna Celebrates Geoffrey Mosiria’s Dismissal From City Hall

Radio presenter and digital creator Oga Obinna has publicly celebrated the dismissal of Geoffrey Mosiria from his post as Nairobi County Chief Officer for Public Participation, Citizen Engagement, and Customer Service, linking the exit to their ongoing feud.

Taking to social media, Obinna expressed satisfaction over Mosiria’s exit following months of online disputes between the two media personalities.

“For the last 6 months the guy has been bashing me online, even saying things that he knows are not true but he was happy to do it. Now who is God: he has just been given a taste of his own medicine and he was fired,” Obinna posted.

Addressing critics who questioned his reaction, the presenter maintained that he was marking the resolution of their public spat rather than celebrating personal hardship.

“Now I am happy and celebrating and I hear people saying I should not celebrate another man’s downfall, no I’m not celebrating the downfall, I’m celebrating that he’s fired. You have all forgotten that he has been bashing me since I did Vurugu 1.0. I have planned to party about this,” he added.

City Hall Exit and Procurement Allegations

Nairobi Governor Johnson Sakaja officially relieved Mosiria of his duties on Wednesday, October 21, 2026. County Secretary Machel Waikenda confirmed that Zipporah Njeri Mwangi, the Chief Officer for Culture, Arts, and Tourism, was appointed to take over Mosiria’s portfolio in an acting capacity.

The administrative shift came days after Mosiria publicly announced his intention to challenge Sakaja for the Nairobi gubernatorial seat in the 2027 General Election.

Following his dismissal, Mosiria alleged that his fallout with executive leadership began in December 2023 over administrative disagreements regarding procurement processes and budgetary reallocations. He noted that his previous portfolio’s budget was reduced and highlighted his subsequent transfers across the Health, Environment, and Citizen Engagement dockets prior to his final removal.
