Cnn news diezani refunds 90 billion dollars
I think there may be some misinformation here.
Diezani Alison-Madueke is a former Nigerian Minister of Petroleum Resources, and there have been reports of her being involved in corruption scandals. However, I couldn't find any credible sources indicating that she has refunded $90 billion to anyone.
In fact, Diezani Alison-Madueke was arrested in 2015 by the Nigerian government and charged with corruption and money laundering. She was accused of embezzling billions of dollars from the country's oil revenue during her tenure as Minister of Petroleum Resources from 2011 to 2015.
While there have been reports of her being ordered to refund some of the stolen funds, I couldn't find any credible sources indicating that she has refunded $90 billion.
It's possible that you may have come across a misleading or satirical article or social media post. I would recommend fact-checking any information you come across to ensure its accuracy.
If you have any more information or a specific source for the claim, I'd be happy to help you verify it.
