Sources within the Presidency said the action signalled the enormity of the decision President Kenyatta has made in relation to his case at the International Criminal Court.
He was later expected to address a joint special sitting of both Houses of Parliament at 3pm on the issue.
There has been strong indication that President Kenyatta will travel to The Hague, after Chief Whip Katoo ole Metito led hundreds of MPs to the Dutch embassy to seek visas last week.
On Sunday, CORD lawmakers said they would boycott the address in Parliament since the ICC issue was not a national dilemma but a personal one facing President Kenyatta.
