Trade Cabinet Secretary Peter Munya has said that he never notified Deputy President William Ruto about his date with detectives from the Directorate of Criminal Investigations (DCI) on Monday.
Munya and his Health counterpart Sicily Kariuki, Joe Mucheru (ICT) and James Macharia (Transport) have been implicated in an alleged plot to assassinate Ruto.
Also implicated in the scheme are other top state officials from the Mt Kenya region, including Principal Secretaries and parastatal heads.
Asked if he notified Ruto of his summon alongside Kariuki and Mucheru, he said that he did not see the need to reach out to a man whom he is being accused of planning to kill.
"The thought of reaching out to him did not arise because I thought, what am I reaching about really? (sic) I have been accused of wanting to kill him," he said in an interview on Citizen TV's News Night, Tuesday night.
The CS who insists that he is innocent, and has never taken part in any plot of such nature added that he was summoned through a text message, which caught him unawares and left him shocked to an extent of doubting it.
"I was shocked. In fact, the moment I received the text message, at first, I thought it was fake," he added.
The issue has since aroused reactions from politicians, with a section, especially Ruto's critics, accusing him of playing games.
Macharia who is out of the country is yet to comment on the issue.
