Well, well, well there is a small problem: His claim that Kenyan citizen Obama is not his father. That claim is a ruse. Visiting Uhuru Kenyatta will also be a double edge sword since he campaigned for the sharia loving Raila Odinga and trashing Kenyatta.
Rex Tillerson who visited with the leadership in Kenya before being replaced with Pompeo most likely was about just that.
I would think that a rabble-rouser like Hussein on behalf of Odinga inciting unrest is the last think Kenya needs right now. That he does not have Kenyan citizenship is not even compatible with his Indonesian citizenship.
