Sifuna is the current Nairobi Senator elected in 2022 under the Orange Democratic Movement (ODM) party. He also doubles up as the party Secretary General.
Professionally, Sifuna is a trained lawyer and was previously a law practitioner before he later joined politics as a full-time career.
As a lawmaker, Sifuna has been at the forefront of challenging the government over issues affecting Kenyans. His brand of leadership makes him one of the most celebrated politicians.
A survey report released in September this year ranked Sifuna as the best-performing senator in the country.
Leeway Africa Research Agency gave the legislator an approval rating of 70.1 per cent, edging out Kericho counterpart Aaron Cheruiyot, who followed closely at 69.7 per cent. Kisumu senator Tom Ojienda came in third with 69.0 per cent.
Despite facing harsh criticism from a section of politicians and other leaders within the government, Sifuna has been vocal about critical issues, particularly those affecting the Kenyan youth.
As the ODM Secretary General, Sifuna, in July this year, challenged the older generation to give youth a chance to decide their future.
