Buhari mourns mobolaji johnson

I think there may be a mistake here.

Mobolaji Johnson was a Nigerian military officer who served as the Governor of Lagos State from 1967 to 1975. He passed away on September 1, 2019, at the age of 85.

However, I couldn't find any information on President Muhammadu Buhari mourning Mobolaji Johnson. It's possible that you may have come across a false or outdated news report.

If you could provide more context or clarify what you're referring to, I'd be happy to help you further.
