They also passed a vote of confidence on Senate President Bukola Saraki and his deputy, Ike Ekweremadu,
The move came as officials of the Economic and Financial Crimes Commission (EFCC) interrogated Toyin, wife of the Senate President for about six hours over alleged corruption.
Mrs. Saraki arrived the headquarters of the Commission in Abuja with a crowd of supporters, some of whom found their way into the premises.
She was invited for questioning over alleged shady contracts during her husband’s tenure as governor of Kwara between 2003 and 2011.
The invitation was in relation to alleged contracts executed by companies said to be linked to her while her husband was Kwara governor.
Mr Wilson Uwujaren, the spokesman of the EFCC confirmed the interrogation of the former Kwara first lady.
Uwujaren said “Mrs. Saraki was in our office for questioning following an earlier invitation sent to her over allegation of corruption.
“I cannot speak further on the issue because I am currently not in the office and don’t have further details on the questioning.’’
The former first lady in a statement issued by her NGO, Well Being Foundation, after her interrogation, pledged to support and cooperate with the EFCC in ensuring credible investigation into the allegation.
The statement said Saraki had surrendered herself to the EFCC in line with her believe in transparency and accountability.
A group of senators, operating under the tag ‘Like Minds’, in a statement signed by Dino Melaye, expressed surprised that the interrogation is coming four years after the Sarakis left Kwara Government House.
Claiming that they did not want to make any hasty conclusion, the lawmakers urged the Commission to perform its lawful duties without any form of external control.
