Buhari dropped the hint in one of the interviews he granted one of the foreign media in his hotel shortly before departing New York.
Confirming his resolve to block all avenues of looting in the nation's oil wealth, Buhari said: “I will serve as the Minister of Petroleum Resources myself.”
The nation’s petroleum sector has been said to be enmeshed in corruption with millions of dollars said to be missing in the Nigerian National Petroleum Corporation.
After assuming office, he sacked and replaced the management of the company. The new management had started a general reorganisation of the firm.
Buhari had on Monday said the trial of those who looted the NNPC would commence soon in courts.
