The President made the allegation on Friday when he received the Buhari Media Organisation at the Presidential Villa in Abuja.
He claimed that the opposition looted so much money before he assumed office and that his administration might not be able to recover all and might use same against his government.
“The oppositions, now, are sitting on incredible resources which I am afraid we cannot get at it all,” President Buhari told the group.
“For that reason, they are in a position to sponsor mischief from different angles which in spite of the incumbency of the government, we cannot absolutely stop.”
President Buhari, however, urged members of the organisation to continue to support his administration in recovering the looted resources as much as they can.
He further praised the support group for its steadfastness, moral uprightness and sacrifice to the nation.
