James Orengo with the opposition coalition says it wants to look at activity the day of the vote and the next day to confirm whether alleged hacking took place.
"No Kenyan should die because of an election".
Odinga's complaints of election irregularities have stoked fears of aggrieved supporters taking to the streets in a scenario reminiscent of 2007's post-election violence. The IEBC's electronic voter identification kits did not work in more than half of all polling stations, and the mobile phone transmission system for results functioned so poorly that it had to be abandoned.
On 9 August, the day after the election, NASA released a 52-page computer log that they claim shows the use of Chris Msando's credentials to hack into the voting database in the hours following the close of the polls, and the re-writing of the results to hand the presidency to Uhuru Kenyatta for a second term.
The envoys said no election is ideal, whether in their own countries or in Kenya, noting that a range of worldwide and domestic observer missions have praised the IEBC for its work in exceptionally challenging circumstances. Kenya dropped six places in Transparency International's Corruption Perceptions Index past year, putting it among 30 countries seen as the world's most corrupt. "One can conclude they [electoral commission] are not keen on taking our concerns seriously", Musalia Mudavadi, a senior official of the National Super Alliance (NASA) and former Kenyan vice president, said.
Preliminary results show the incumbent, President Uhuru Kenyatta, leading by nine percentage points with almost all the votes counted.
In response to Odinga's claims, IEBC Chairman Wafula Chebukati said it appears the opposition's issues stem from results transmission rather than with the whole election.
They stated that NASA allies in the IEBC have leaked the real numbers to them, which show that Kenyatta is not ahead by 1.4 million votes as the IEBC's website shows - rather it is Odinga ahead of Kenyatta by 286,298 votes. "Leaders above all need to make that clear".

But Odinga supporters, many of them members of his Luo tribe or other allied tribes, said they are being robbed of yet another election.
"With regards to the allegation of hacking, it was brought to our attention...and as President Thabo Mbeki indicated; our observer missions are not clothed with the investigative capacity to even investigate those allegations".
He termed the decision to announce the victor by IEBC as "a charade" and also accused worldwide observers for declaring the elections free and fair.
Violence broke out this week in some opposition strongholds in parts of the capital, Nairobi, and elsewhere. Around 1,200 people were killed in a campaign of ethnic violence that followed.
