The IEBC had invited the two presidential candidates to a joint meeting on Wednesday with an aim of discussing contentious issues regarding the repeat presidential poll scheduled on October 17.
The Jubilee team urged the electoral body to change the date of the meeting as the full judgement on the NASA election petition is expected from the Supreme Court on Wednesday.
"We acknowledge receipt of your letter dated September 14, 2017, on the subject of the fresh presidential election calling for a consultative meeting slated for Wednesday, September 20, 2017. We, however, request to have the said meeting postponed and held at an appropriate future date.
"We will need to go through the detailed judgement so that our contribution can be more constructive," the letter read in part.
The President further hit back at Mr Odinga during a meeting held with leaders from Narok County at State House on Tuesday.
"The threats by the Opposition amounted to bullying, intimidation and rogue politics, but will amount to nothing," the President declared, responding to the NASA leader's accusations that IEBC and Jubilee colluded with Safran Morpho to steal Odinga's votes.
Uhuru further bashed the Opposition for sentiments expressed concerning a change of the October 17 poll date and threats to ensure no election is held on that date.
"We are telling our opponents to stop intimidating Kenyans. Nobody can block the election. And we will not give in to any kind of intimidation from anybody," President Kenyatta stated.
