This guy is an idiot. His twitter account is verified. He is in effect acknowledging that he has been served.
He also think because he lives in state house and has security he cannot be served. That ended when Kibaki failed to serve Moi. Now the law allows litigants to serve each other through the media - including social media!
He does not understand that what is coming would completely ruin him. At his age to be found by a court to be a liar is first of all to guarantee that his public job is gone! He cannot serve on a board of governors of a school unless nobody knows or is not interested in kicking his ass. He can witness his own wife being raped by Pundit but cannot be put on the witness stand. If an advocate tries, he risks contempt proceedings and referral to the LSK.
That is why most people opt to settle out of court.
