Nyamira Senator Kennedy Mong'are Okong'o has dismissed claims that he was heckled at a purported fundraiser at Kebirigo market last week.
Mong'are is now seeking an apology from the story's writer for falsifying information, noting that he never attended the alleged function.
He said the online story was malicious and aimed at tarnishing his reputation.
"Journalists are trusted people and should at all costs practice responsible journalism by writing factual information," said Mong'are on phone on Monday.
Mong'are said the alleged fundraiser for boda boda operators was a fabrication, adding that Kebirigo market residents respect him and was shocked to read the story.
"Kebirigo area is my stronghold and when somebody says I was criticised I wonder where we are heading to," added Mong'are.
He asked journalists not to accept to be compromised to taint people's names and instead verify information before going to press.
