This comes after Senate Public Accounts Committee found him guilty of verbally assaulting the governor. 

The committee chaired by Kisumu Senator Prof Anyang Nyong'o recommended he apologise to the governor and the Senate but the senator is now adamant to do that. 

"I will not apologise to Kidero and I will not apologise to the committee," remarked Sonko. 

Sonko was under probe by the committee for a scuffle that occurred between him and Kidero during a committee hearing on June 15. 

The two exchanged blows at a Senate PAC session where Kidero was being quizzed over the county's financial spending for the 2013/14 financial year. 

The committee found him guilty of verbal assault, but absolved him from accusations of physical assault on Kidero. 

The outspoken Senator accused Kidero of using his financial muscle to get the report done in his favour and also castigated the committee for 'betraying' him. 

"He is always a winner. He always emerges a winner. This is the power of the money working," he added.
