The Senate had suspended treating the nominees' list sent by Buhari in protest against the retention of Ibrahim Magu.
It was gathered that eight out of the nominees were screened on Wednesday, May 10.
The exercise will continue on Thursday, May 11.
On March 28, 2017, the Senate suspended treating the nominees' list sent by Buhari in protest against the retention of Ibrahim Magu as the Acting Chairman of the EFCC despite his two-time rejection by the upper chamber.
The legislature, which called for the removal of Magu, gave the Presidency two weeks to do the needful.
The lawmakers, however, made a U-turn on May 2, as they decided to consider Buhari's request.
