Nominated Senator Millicent Omanga, a vocal ally of Deputy President William Ruto, is among Senators supporting the motion to remove Kithure Kindiki as Deputy Speaker.
A list that surfaced on Wednesday, May 20 indicated that 48 Senators had expressed their support for the motion, appending their signatures and I.D numbers to the document.
A Senator whose name features on the list spoke to Kenyans.co.ke on May 20, on condition of anonymity, disclosing that the list was genuine.
The motion to oust Kindiki was filed by Majority Whip Irungu Kang'ata in the Senate on Tuesday, May 19.
Omanga's name stood out as allies of the Deputy President have opposed changes in the leadership of the Majority side in the Senate, which started with the removal of former Majority Leader Kipchumba Murkomen and former Majority Whip Susan Kihika.
Other than Jubilee legislators, the motion to remove Kindiki is backed by several leaders from opposition parties including the Orange Democratic Movement (ODM) and Wiper.
The purge seen to be targeting the Deputy President's men is expected to proceed to the National Assembly where his allies hold key positions.
Omanga was among 5 Nominated Senators ask to provide Show Cause letters to the Jubilee Party after failing to attend a Senate Parliamentary Group (PG) meeting at State House, Nairobi on Monday, May 11 to approve the changes.
Jubilee Secretary General Raphael Tuju revealed that the party had recommended to its disciplinary committee that Omanga, Iman Falhada Dekow, Waqo Naomi Jillo, Victor Prengei and Mary Yiane Seneta, be removed
Facing expulsion from the party, she claimed in a radio interview on Thursday, May 14, that she had received no communication about the State House meeting.
"It's not true. I was not invited to State House. I came to know about it through social media. Maybe some Senators were informed and others were not. I did not receive an email or SMS. My personal assistant was neither informed.
"To say the truth, I have not received that letter. I have seen it in newspapers, the television and social media platforms. I tried reaching out to Tuju but he was unavailable. I left him my number and a text message.
"We are in a democratic world and we need to have discussions whenever an issue arises. I oppose the changes conducted at State House -Senators Kipchumba Murkomen (Elgeyo Marakwet) and Susan Kihika (Nakuru) were ousted as Senate Majority Leader and Majority Chief Whip- as I don't know what happened and how it was conducted," she maintained.
