Matiang'i served as a minister in three different portfolios, including Education and Interior dockets, between 2013 and 2022 under former president Uhuru Kenyatta's administration.
The current administration, led by President William Ruto, accused Matiang'i of targeting politicians allied to the Head of State in the run-up to the August 9, 2022 General Election.
Some of Kenyatta's lieutenants are claiming that the Ruto administration is out to revenge on the former president's close allies.
