Have you ever heard anywhere on this earth where "strangers" attend cabinet meetings? It happened only before in Meru County under the current pastor governor and led to a mutiny.
Nothing stops Ruto from appointing "genius" David Ndii to the cabinet. Ruto just has to follow procedure laid down by the constituition.
This is an act of self sabotage. I would say whenever they have those cabinets meetings they should be able to bring in expects on subject matter of the day. David Ndii brain power is equivalent to 75% of that cabinet. Why would you not want someone like that in the cabinet meeting?
