Raila Odinga's NASA will on Monday expose alleged threats by US government to Ex-IEBC commissioner Roselyn Akombe.
A furious Odinga accused Washington DC of meddling in internal affairs of the country adding that 'Kenyans will not be dictated' by US.
"America cannot dictate us on what we are supposed to do. We are a sovereign nation and they should keep off our issues," he said.
Western envoys led by US ambassador Robert Godec had demanded that Raila to recognise Uhuru Kenyatta as president, a statement that has not gone well with opposition.
Top strategist Norman Magaya linked the August bungled elections to external interference besides claiming that US had threatened Ms. Akombe, who now serves at UN.
"On Monday, we shall tell who Robert Godec and Nick Hailey are. From threats to Akombe to sustained election fraud cover up.
"We shall lay it bear. You have opened this door and you must walk all through," said Magaya, a confidant of Raila.
For months now, Raila has been at loggerheads with Washington DC over Kenyan elections, insisting that US had abandoned democracy and instead, joined 'dark forces'.
