A section of opposition MPs wants the US ambassador to Kenya recalled for what they termed exhibiting extreme bias when discharging his duties.
Ugunja MP Opiyo Wandayi, who spoke on Monday on behalf of Nasa legislators said a draft petition is being prepared to be presented to the relevant committee of the US Senate as a formal protest note over Mr Robert Godec's behaviour.
"More like-minded MPs and I will petition the US government using the relevant and official channels to raise our concerns over this grave matter," he said.
"Mr Godec's continued stay in the country is injurious to the long-term relationship between the people of Kenya and the US," Mr Wandayi, who is also the secretary for political affairs in ODM, added.
Though Mr Wandayi noted that Nasa had no issue with President Donald Trump's administration, he accused Mr Godec of reducing himself as the US envoy to "only a section of Kenya". He added that the vast majority of Kenyans have no confidence in him.
"We are aware that he seems to have profound vendetta against Nasa leader Raila Odinga after the last general election. This was confirmed on January 30, when Mr Godec convinced the other Nasa principals to isolate Mr Odinga as he took "oath" as the people's president," said the MP.
