President Buhari had been accused of complicity in the matter after many noted that he was too silent on the issue of the killings by herdsmen, thereby leading to suggestions that the President was being sympathetic to the herdsmen.
But Kalu has said that the Buhari he knows cannot support killing of citizens under his administration.
Kalu was speaking at his residence in Abuja while hosting the outgoing Czech Ambassador to Nigeria, Pavel Mikes, to a dinner.
Those who attended the dinner included the Secretary to the Government of the Federation (SGF), Boss Mustapha, the National Chairman of the All Progressives Congress (APC), Adams Oshiomhole, National Chairman of the Reformed All Progressives Congress (R-APC), former National Chairman of APC, John Odigie-Oyegun and Minister of Labour, Chris Ngige.
Kalu said “It’s surprising when people will accuse our President of supporting herdsmen. It’s a sick man or woman that will be able to say that.
“I don’t know why a President of Nigeria would be expected to aid people to kill his citizens. It’s embarrassing to even hear that. There is no way any man elected by the people will leave…. and be doing other things.
“The issue of herdsmen has become a big challenge to us since government dismantled Boko Haram. It’s embarrassing to continue to see where human being will kill their fellow human beings. It is not acceptable to anybody created by God,” Kalu said.
Being a former governor himself, he charged state governors to do more to end the series of herdsmen killings in the country.
President Buhari has come out in recent times to slam reports of him being involved in the herdsmen killings, describing such allegations as unfair.
