You will recall that obama state department expells 35 russian deplomats base on election medling https://www.google.com/url?sa=t&source=web&rct=j&url=https://amp.theguardian.com/us-news/2016/dec/29/barack-obama-sanctions-russia-election-hack&ved=2ahUKEwjB7euErvnfAhXbVxUIHZEhAbwQFjAGegQIBhAB&usg=AOvVaw1emlz1p69LwcX3UwM6YpwI&ampcf=1. If diplomatic immunity didnt save these russians from expelling in usa how come its now save atiku from expelling since there is a substantial evidence against him and saraki diplomatic passport covers him?
A country is able to devise its official diplomatic imunity( which i know the present administration can do anything just to fustrate their opponents). Are they really ashame to admit that atiku donot have any case to answer in the US or they are just doing every thing possible just to ease their pain that he s actually untoucheable in the US.

They know Atiku has no case to answer. They just want to lie so they can destroy Atiku.

It is easier to destroy Atiku than show what they have achieved because they have achieved nothing than poverty.
