Mr Odinga has in the past defended his handshake with the President, saying it was not meant to push Dr Ruto out of Jubilee.
Dr Ruto attended the event accompanied by leaders including Governors Joyce Laboso (Bomet) and Ferdinand Waititu (Kiambu) and Senators Susan Kihika (Nakuru) and Kipchumba Murkomen (Elgeyo Marakwet).
A number of members of parliament including Charity Gathambi (Njoro), Kareke Mbiuki (Maara) and Ms Jumwa were also present.
The leaders launched a scathing attack on Mr Odinga, accusing him of rocking the boat in Jubilee to frustrate the achievement of the President's Big Four agenda.
Regarding the next election, Governor Waititu maintained that Central voters would stick to the succession deal between President Uhuru and Dr Ruto.
“The people of Mount Kenya still believe in the succession plan set in 2012. Anything short of that will not be accepted," he said and vowed to continue campaigning for Dr Ruto.
The Njoro MP accused Mr Odinga of using the handshake to undermine Jubilee leadership.
Senator Murkomen told voters that no one would be forced to choose a candidate in the next presidential election.
"The propaganda being spread by our opponents, who claim some communities will be intimidated and influenced in their choices, is meant to dent the Deputy President’s bid to succeed President Kenyatta,” he said.
Ms Jumwa, who arrived without a bodyguard, said she would continue backing Dr Ruto’s presidential ambition.
None of the politicians commented on the withdrawal of security guards attached to Dr Ruto's allies.
