Senate Majority Leader Kipchumba Murkomen now claims that the Directorate of Criminal Investigation (DCI) doesn't have the moral authority to handle matters impunity.
The Elgeyo Marakwet Senator has been leading a group of Rift Valley leaders who have mounted an offensive on the George Kinoti-led institution for allegedly being bias in the ongoing purge on graft.
Speaking at Kiwawa Boys High School in the county Saturday, he wondered why the DCI is yet to file charges against opposition leader Raila Odinga over his 2018 mock presidential swearing-in.
"If they are not going to arrest him then there is no need of raising an alarm against impunity and yet the opposition leader himself is a free man and has no authority to lecture people on impunity,” he was quoted by the Standard.
This comes at a time when Raila has also been leading a campaign against corruption in the country.
Most of the scandals have landed at Deputy President William Ruto's doorstep and has seen himself (Ruto) and his allies blamed for most of them.
Raila on January 30 last year swore himself in at Uhuru Park, Nairobi county, in an event that was attended by thousands of his supporters and hundreds of allies and associates.
This was despite warnings from the government that the same would amount to high treason which is punishable by death, only 2 months after rejecting President Uhuru Kenyatta's reelection.
However, no charges have been pressed against him.
Murkomen was speaking when he accompanied Ruto for a fundraiser for the construction of a block at the school.
