The senate has yet again rejected the nomination of Ibrahim Magu as chairman of the Economic and Financial Crimes Commission (EFCC).
Magu was rejected after the senators voted against his confirmation.
Dino Melaye, senator representing Kogi west, had cited a fresh security report from the Department of State Services (DSS).
The lawmakers said the anti-graft czar “failed integrity test.”
The senate had rejected Magu’s nomination in December after the DSS indicted him in a report.
The anti-graft czar was accused of corruption and “gross violation of human rights”. He was also alleged to be in possession “of undeclared pieces of property.”
After denying all the allegations, President Muhammadu Buhari renominated him in January.
Magu was appointed in November 2015, following the sack of Ibrahim Lamorde.
