Mr Linturi urged the Gema community to rally behind the leader that Mt Kenya East will select.
Mr Muturi, who kept off the debate, gave Sh500,000 from Dr Ruto and his own donation of a similar amount.
A section of leaders from Meru and Tharaka- Nithi County has endorsed Deputy President William Ruto for president in 2022.
They have, however asked the DP to pick National Assembly Speaker Justin Muturi as his running mate.
Meru Senator Mithika Linturi, MPs Kirima Nguchine (Central Imenti), Mugambi Rindikiri (Buuri), John Paul Mwirigi (Igembe South), Gitonga Murugara of Tharaka, said Mt Kenya East voted as a bloc and should have one of their own as the deputy president.
Speaking at St Mathews Mariene AIPCA Church, in Imenti Central, Meru County, on Sunday, the legislators said they had supported leaders from the larger Central region and it was the time for them to reciprocate.
Mr Linturi said it was important to openly debate the 2022 succession to enable the region prepare to position itself when President Uhuru Kenyatta retires.
“It is no longer a secret, the Constitution does not allow President Kenyatta to run in 2022. We should not shy away from discussing the 2022 politics. We should support our people since this region has good leaders who can promote their welfare,” he said.
Mr Linturi urged the Gema community to rally behind the leader that Mt Kenya East will select so as to reciprocate the support the Embu, Meru and Tharaka-Nithi has been giving to Central Kenya.
