Sani said Buhari, who is the Minister of Petroleum Resources, should have addressed the issue “by now.”
The lawmaker stated this while contributing to a debate on a report for the payment of subsidy arrears to some oil marketers on the floor of the Senate on Thursday.
He also urged the country to emulate Ghana and start refining its petroleum products.
Sani stressed that until Nigeria starts refining its crude, the “circle of exploitation” would continue.
According to Sani: “The issues of subsidy has been lingering. Until we start refining our crude oil this circle of exploitation will be ongoing.
“The president is the minister of petroleum resources, we thought by now he should have been able to address these issues.
“Refineries built more than three, four decades ago are still lying fallow and we are waiting for Dangote to finish his refinery.
“Refining crude is not rocket science rocket science, if Ghana is refining its product why are we still not. A government that opposes subsidy is still paying for it, when will this end?”
