Tana River Senator Danson Mungatana has filed a censure motion against Deputy President Rigathi Gachagua.
The lawmaker said he filed the motion with the office of the Speaker of the Senate early Monday.
He alleges the DP has engaged in divisive politics and betrayed his oath of office among others.
A censure motion is a debate to show strong disapproval against the conduct of a state officer; it's not an impeachment motion.
The DP is facing growing isolation amid an alleged impeachment motion, which has served to further alienate him in government and has somewhat resorted to fighting back by endearing himself to the voters through public rallies.
DP during an interview on Citizen TV on Friday lamented about being removed from President William Ruto's diary WhatsApp group.
The DP said that the move to remove him and some of his staff has made it difficult to work efficiently.
He, however, said that he would find the right time to talk to the President and sort out the issue.
"I always align my diary with that of the President, all the time, and as long as I'm aware of that function, I align accordingly. Sometimes if I'm not aware, I'm unable to align because I also have my programme," he said during the interview.
Head of Creative Economy and Special Projects in the Office of the President, Dennis Itumbi, however said the group was deleted after highly classified documents were being shared to other groups.
Gachagua also revealed reasons why a section of leaders want him out of office.
He said that due to his nature of being truthful, he is being attacked.
"They say that I'm high-headed, that I'm too people-centered, and that I listen to people too much. That I'm asking people to listen to what Kenyans are saying. I don't think it is a crime," he said during the interview.
National Assembly majority leader, Kimani Ichung'wah has, however, dismissed claims of an impeachment motion against Gachagua.
Speaking in Siaya, Alego Usonga, Ichung'wah stated that no MP has attempted to collect signatures for such a motion.
"As the majority leader, I can tell Kenyans there has never been any impeachment plans against him (DP)," he stated.
The DP said he will soon start giving Kenyans regular updates on the intricacies within the government.
He said he would keep Kenyans informed about happenings in the inner circles within the Kenya Kwanza administration.
“Going forward, in the next few weeks, I will be talking to my supporters telling them what is going on, what is being planned and what is likely to happen so that they are aware,” he said.
Gachagua maintained that he has the responsibility to tell the people about the goings-on in government.
He further said that what is happening to him with the current administration is worse than what happened to President William Ruto when he was the second-in-command.
Gachagua over the weekend asked President Ruto to unite his Kenya Kwanza Alliance party.
Speaking at PEFA church in Thika, Kiambu county on Sunday, the DP said this is for the sake of the country's development.
"Ningetaka kuuliza rais wetu ajaribu tu aweke nyumba yake pamoja tuweze kufanyia wananchi kazi," he said.
This loosely translates to: "I would like to ask our President to try and put his house in order so we can work for the citizens."
Gachagua reiterated that the Executive should focus on developing the country.
