President Muhammadu Buhari has ordered an investigation into how the National Intelligence Agency came to claim the money and whether any laws were broken, a government statement said.
Mr. Buhari's statement on Wednesday gave few details of the alleged corruption, except that it involved the awarding of contracts under a Nigerian government program, the Presidential Initiative on the North East.
President Buhari, in a statement signed by his Special Adviser on media and publicity, Femi Adesina Wednesday directed that Lawal will remain suspended pending the outcome of the investigation which bothers on alleged violations of law and due process made against the SGF in the award of the contracts.
Mr Oke is to face probe over the huge cash discovered at an Ikoyi, Lagos, apartment by the Economic and Financial Crimes Commission, which he claimed belonged to the NIA, while Lawal is under probe for mismanagement of funds.
Other members of the committee are the Hon.
Mr. Buhari has ordered both of the investigations to report to him within 14 days.

"Is their presidential committee also going to tell Nigerians those who abandoned N49 million cash in an airport that has CCTV cameras?"
Journalist: Have you been informed of the suspension?
Lawal: I have not seen it. I have not seen the press release so I can not comment on it.
Vice President Yemi Osinbajo yesterday afternoon held a meeting with the Mr Babachir. I used to come here even before I was made SGF.
The governor wondered why the All Progressives Congress-led Administration unleashed EFCC and DSS on opposition figures and judges under investigation, while setting up a committee to investigate its officials accused of corruption. He said, in January, that the Senate did not extend principle of fair hearing to the suspended SGF and that the damning report itself was a "minority report".
" The Senate and the Commitee have nothing personal against the SGF or any person affected, but we simply did our job in conformity with our constitutional responsibilities and the moral calling of our conscience".
"We can not jubilate because a mighty mortal is caught in the trap of his fate, we are neither saints nor angels, but we have a duty to raise a card a blow the whistle". The Senate in a unanimous resolution requested President Buhari to sack the SGF. Ayo Oke, who was also suspended, was seen around the Vice President's office immediately after the departure of the SGF.
