The Kiharu MP threw his hat in politics in 2017 under the Jubilee party ticket, winning the seat with a landslide, against his competitor.
Previously, he was an economics graduate from Kenyatta University who was a student leader while at the Institution. He is an entrepreneur with interests in stock brokerage, communication, construction, civil works, water engineering and drilling
The MP is an ardent supporter of Deputy President William Ruto and does not shy off critiquing President Uhuru Kenyatta and ODM leader Raila Odinga for the March 2018 handshake.
In October 2020, Interior General of Police directed Nyoro be arrested for allegedly mobilizing goons who causing mayhem at Kenol, Murang'a County.
The chaotic scenes in the area resulted in the death of two people and left several others nursing injuries. Nyoro, however, said he had nothing to do with the chaos.
The MP is famous for the Anti-corruption and Economics Crime Amendment Bill he proposed in 2019. The bill stipulated stringent penalties including execution for those convicted of corruption in Kenya.
The bill was slammed by ODM leader Raila Odinga who indicated that it was a ploy to clip powers of the Directorate of Criminal Investigations and Directorate of Public Prosecutions in handling corruption cases
