Buhari call donald trump to congratulate him on his victory

I think there may be some confusion here.

Donald Trump did not win a recent election. He was the 45th President of the United States, serving from 2017 to 2021. Joe Biden is the current President of the United States, having taken office on January 20, 2021.

Additionally, I couldn't find any evidence of Nigerian President Muhammadu Buhari calling Donald Trump to congratulate him on a victory. While both leaders have had interactions and conversations, I'm not aware of any specific instance of Buhari congratulating Trump on a victory.

If you have any further information or context about this, I'd be happy to help clarify!
