Mr Duale said he will not allow “hired people” to speak for the party with intent to break it up.
The Garissa Town MP was accompanied by MP Kassim Tandaza (Matuga), Mr Khatib Mwashetani (Lunga Lunga), Mr Suleiman Dori (Msambweni), Mr Stanley Muthama ( Lamu West), Mr Omar Mwinyi ( Changamwe) and Tana River Woman Representative Rehema Hassan.
Other leaders who spoke at the event warned Mr Atwoli to tame his tongue and concentrate on the welfare of the workers and leave Mr Ruto alone.
Mr Muthama lashed out at Mr Atwoli, saying Lamu people would not welcome him “if he is coming to insult other leaders”.
“Atwoli spoke nonsense when he came to our county. Instead of speaking about what had taken him there, he went to insult people but we are telling him that we will not spare him. We will deal with him,” said Mr Muthama.
Mr Mwashetani accused Mr Atwoli of peddling lies against Mr Ruto over corruption.
“If you think someone is corrupt and you have evidence then take it to the Directorate of Criminal Investigations and Director of Public Prosecutions. If Atwoli is interested in politics, he should say so that we deal with him,” said Mr Mwashetani.
