Obasanjo celebrates his 83rd birthday president buhari greets congratulates him

I think there may be some confusion here.

Olusegun Obasanjo, the former President of Nigeria, is actually 84 years old, not 83. He was born on March 5, 1937.

As for President Muhammadu Buhari's greeting, I couldn't find any official statement or tweet from the President congratulating Obasanjo on his birthday. However, it's possible that the President may have sent a private message or made a public statement acknowledging Obasanjo's birthday, which I'm not aware of.

It's worth noting that Obasanjo has been a prominent figure in Nigerian politics and has had a complex relationship with President Buhari, who has been critical of some of Obasanjo's actions and decisions during his presidency. Despite this, it's possible that the President may have sent a congratulatory message or made a public statement acknowledging Obasanjo's birthday, even if it's not publicly known.
