The embattled senator is a Peoples Democratic Party member representing Adamawa North Senatorial District, who allegedly slapped the saleswoman at a sex toy shop sometimes in May this year.
The President of the Senate, Ahmad Lawan, constituted the panel following a point of order raised by the Senator representing Kaduna Central, Uba Sani.
The Senate Leader, Abdullahi Yahaya; Minority Leader, Enyinnaya Abaribe; and Senator Opeyemi Bamidele, supported Sani by condemning the alleged action of the Senator.
The President of the Senate confirmed that he had been inundated with calls from concerns Nigerians within and outside the country asking the Senate to explain what happened.
Lawan said it would be unfair on either the Senator or the assaulted lady if the Senate should pass a judgment immediately based on the viral video clip on the social media.
He therefore asked the ad-hoc committee to probe the issue critically by inviting both parties and submit its report within two weeks.
Other members of the panel are, Senators Oluremi Tinubu, Mathew Urhoghide, Stella Oduah, Dauda Aliu Jika, Sani Musa, and Danladi Sankara.
