Bungoma MCAs on Tuesday stormed Governor Wycliffe Wangamati's office demanding that he leaves for failing to initiate development projects since he was elected.
At least 42 out of 63 MCAs have signed a petition to impeach the county boss.
They snubbed a special sitting of the assembly which was called to approve the names of chief officers and other county staff for vetting.
Members of the public joined the MCAs in the demonstrations as they demanded to be addressed by the governor. Operations at the county assembly were brought to a standstill.
The MCAs accused the governor of having a poor development record and of high-handedness in the discharge of his duties.
Tuti Marakaru MCA Joseph Nyongesa refuted claims by the governor that the county government has disbursed Sh34 million in every ward for development.
"He is setting us up against the public. We are going to ensure he leaves office before he brings us down," Nyongesa said.
Saboti Ward MCA Wamusai Simiyu said: "We are surprised that one year down the line the governor has not initiated. He is appointing his cronies."
Simiyu, who is also the deputy speaker, said Bungoma residents were tired of Wangamati's rhetorics.
Wangamati could not be reached for comment. His phone went unanswered and he never replied to short text messages.
Director of communication Tim Machi told the Star on Wednesday the governor "will not respond to street protests". He said MCAs should follow the right channels to air their grievances.
"We will wait for formal communication before we respond. MCAs know the avenues to use if they have an issue with the executive," he said.
Minority leader Francis Chemorion said Wangamati is not doing much to fight corruption.
