Bauchi Central senator, Abdul Ningi, on Tuesday, resumed plenary five days after he was recalled from suspension.
Mr Ningi, a member of the opposition Peoples Democratic Party (PDP), was sighted entering the Red Chamber at 10:40 a.m. He took his seat after exchanging pleasantries with some of his colleagues.
Mr Ningi was suspended on 12 March for three months but was recalled last week by the Senate following a motion by Minority Leader, Abba Moro (PDP, Benue), on behalf of the minority caucus.
He had accused the leadership of the upper chamber of illegally inserting projects worth N3 trillion in the 2024 budget.
The lawmaker said he sought the services of a private auditor to review the budget and discovered some projects that did not have locations.
At the time he made the allegation, Mr. Ningi was the chairman of the Northern Senators Forum (NSF). He resigned from the position over the matter.
