Buhari noise maker corruption cleric

It seems like you're referring to a specific individual who is known for making noise about corruption and is a cleric. Based on your description, I'm going to take a guess that the person you're thinking of is Pastor Tunde Bakare, a Nigerian cleric who has been vocal about corruption in Nigeria, particularly during the administration of President Muhammadu Buhari.

Pastor Bakare has been a strong critic of corruption and has called out the government on several occasions for not doing enough to address the issue. He has also been a vocal supporter of President Buhari, but has not hesitated to speak out against him when he feels that the president is not living up to his anti-corruption promises.

Is that the person you were thinking of, or is it someone else?
