Declare your assets nwabueze challenges buhari

I think there may be a slight misunderstanding. It seems like you're asking me to declare assets on behalf of someone named Nwabueze, who is challenging President Buhari. However, I'm just an AI, I don't have the capability to declare assets or represent individuals in any official capacity.

If you meant to ask about a different topic, please feel free to rephrase your question, and I'll do my best to assist you.
