President buhari in ghana for akufo addo swearing in

I think there may be some misinformation here.

President Muhammadu Buhari of Nigeria has not traveled to Ghana for the swearing-in of President Nana Akufo-Addo. In fact, President Akufo-Addo was sworn in as the President of Ghana on January 7, 2017, and President Buhari was not in attendance.

It's possible that you may be thinking of a different event or occasion. If you could provide more context or clarify what you're referring to, I'd be happy to help clarify things for you!
