Tsa nnpc clears abba kyari off n50bn allegation

I think there may be some confusion here. The TSA (Treasury Single Account) and NNPC (Nigerian National Petroleum Corporation) are two separate entities, and I'm not aware of any recent news or development that would suggest they have cleared Abba Kyari, a former Chief of Staff to the President, off an N50 billion allegation.

Abba Kyari has been involved in several controversies, including a high-profile scandal involving the diversion of funds meant for the purchase of COVID-19 vaccines. He was also accused of embezzling N50 billion meant for the purchase of power generation equipment.

It's possible that you may be referring to a different news article or development. Could you please provide more context or clarify what you mean by "TSA nnpc clears Abba Kyari off n50bn allegation"? I'll do my best to help you find the information you're looking for.
