Peter obi to speak on us nigeria relations at washington event

I think there may be some confusion here.

Peter Obi is a Nigerian politician who served as the Governor of Anambra State from 2007 to 2014. While he is a prominent figure in Nigerian politics, I couldn't find any information that suggests he will be speaking on US-Nigeria relations at a Washington event.

It's possible that you may be thinking of another person or event. Could you provide more context or clarify which event you are referring to? I'd be happy to help you find more information.
