The APC-dominated House recently came under intense public scrutiny following allegations that lawmakers manipulated the 2016 budget to enrich themselves.
The party on Tuesday met with Abdulmumin Jibrin, the lawmaker at the centre of the crisis.
Mr. Jibrin is accusing Speaker Yakubu Dogara and other principal officers of the House of “padding” the budget.
In its latest move, the party on Thursday directed Mr. Jibrin to immediately stop distributing statements to the media with respect to the scandal.
Mr. Jibrin says Mr. Dogara, his deputy, Yusuf Lasun, House Whip, Alhassan Doguwa and Minority Leader, Leo Ogor attempted to smuggle up to N40 billion into the budget.
The lawmaker claims he foiled the fraud, and has circulated several documents to the media purporting to support that allegation.
In its letter Thursday, the APC said the situation in the house was embarrassing to the party.
“Arising from the series of the meeting we held with you over the subject matter, the National Working Committee has decided you henceforth avoid issuing any public statement on this matter.”
The APC also emphasised the scope of its order to Mr. Jibrin’s, saying, “This however, includes statements through social media or other means of transmitting an opinion on the matter to the public, as the party is now looking into it towards finding solution”.
It is not immediately clear if Mr. Jibrin would yield to his party’s latest demand.
Efforts to reach him proved abortive Thursday afternoon.
