Kindiki has served as Senator for Tharaka-Nithi, from 2013 to 2022.
He clinched the seat on his first attempt at elective politics.
He was then elected the first leader of the Majority in the Senate, a position he held until he became the Deputy Speaker after the 2017 general elections.
He was de-whipped from the position in 2020, a casualty of the fall-out between President Uhuru Kenyatta and his then-deputy Ruto.
Before his election, he taught law at Moi and Nairobi universities from 1999.
In 2004 he joined the University of Nairobi where he served until 2005 when he returned to Moi to head the department of Public Law.
He served as Secretary of the National Cohesion in the Ministry of Justice soon after the 2008 post-election violence. He was instrumental in the drafting of the National Cohesion and Integration Act.
However, he resigned after three months and accused the government of lacking the political will to resettle hundreds of thousands of displaced people by the 2007/08 post-poll skirmishes.
He was thrown into the public limelight when Ruto appointed him to his legal team when he faced crimes against humanity charges at the International Criminal Court (ICC).
