In a vernacular video circulating on social media, Kuria is heard chiding Kiambu governor Ferdinand Waititu for criticising him over his presidential ambition.
During a memorial service to mark the second anniversary of Nyeri Governor Nderitu Gachagua's death on Saturday, Waititu told Kuria he was a big joker.
"Moses Kuria hails from Kiambu and we respect him because he is our friend. But I want to put the record straight that there is no confusion at all in the direction that we are headed as a community. We are waiting for that time," he said.
But Kuria retorted, “I am not contesting at your home, leave me alone.”
He said he has looked left and right and realised he's the only politician who can deliver good and services to Kenyans.
Waititu, Speaker of the Senate Ken Lusaka, Governors Mutahi Kahiga (Nyeri) and several other MPs had accompanied DP William Ruto to the event at Karatina Railway grounds.
Kirinyaga governor Anne Waiguru echoed Waititu's remarks and asked Kuria to slow down on his ambition.
She said Mt Kenya had a clear direction on the direction to take come 2022.
"A wise person does not need to be told. When political campaigns begin we shall be there, we know how to campaign and if you look at us you will tell which side we are on," Waiguru said.
Kikuyu town MP Kimani Ichungwa said he would not betray Ruto by siding with Kuria.
"I will be back here during campaigns and at that time you all know whom I will be pitching for and of course it's not the likes of Moses Kuria," he said.
