The committee is investigating corruption allegations against Lawal, in the award of contracts under the Presidential Initiative on the North East (PINE).

The committee, which on Thursday grilled some of officials, is headed by Vice President Yemi Osinbajo. Attorney-General of the Federation Abubakar Malami and National Security Adviser Babagana Monguno, are members.

The separate letters to Lawal and Oke directed the duo to submit all documents relating to award of contracts by PINE and the cash remittances to NIA in the last two years.

The Osinbajo-led panel listed documents to be submitted as follows:

details of appropriated funds in the last two years;
allocation of special funds if given;
approvals for funds and by who;
expenditures; withdrawals from the Central Bank of Nigeria(CBN) if any;
covert operations and for what purposes;
completed and non-completed projects;
list of contracts awarded;
ongoing projects;
and operation of safe houses.

The committee said it expects the two officials to send their responses on or before Monday.

This will be followed by continued questioning of Lawal, Oke and some government officials and agencies whose names have not been revealed.

It was gathered the modalities for their appearance are being worked out by the committee.

Oke had earlier told the panel that former President, Goodluck Jonathan approved a sum of $289 million.

Jonathan was said to have directed that the money be given to NIA from the account of National Petroleum Investment Management Services (NAPIMS),
