In 1980, when he was just 29 years old, he became the youngest MP in Kenya after he was elected to the Ugenya Constituency on a KANU party ticket. However, this was short-lived, as he was among those who were involved in the 1982 coup and later got detained.

In the 1992 multi-elections, Orengo was subsequently elected as the Ugenya Constituency MP on a Ford-Kenya ticket. He served as an MP until 2002, when he contested for the presidency (for the Social Democratic Party) but lost the seat, finishing fourth in the race having garnered 0.4% of the votes.

Since James Orengo joined active politics, he has constantly been in the opposition. Although he vied for the presidency in 2022, he has remained a loyal soldier to Raila Odinga.

After the 2013 general elections, Orengo stepped down as an MP and vied for the Siaya senatorial seat, which he won, and worked in the senate until this year, 2022.

In the just concluded 2022 general elections, he was elected as the Siaya County Governor.

Prior to serving in the Senate, Orengo had previously served as the Minister of Lands between 2008 and 2013.

The accomplished lawyer’s name will be penned down in history books as the senior counsel who led in the petition against the 2017 general elections at the Supreme Court, which he won, leading to the nullification of the re-election of President Uhuru Kenyatta.

Not forgetting, Orengo has fought many court cases against the government during the reign of Daniel Arap Moi, Mwai Kibaki, and Uhuru Kenyatta, and most of the time emerged victorious.

He also worked as a personal lawyer for Rwanda’s President, Paul Kagame.

Thus, it is without a doubt that Lawyer James Orengo is one of the best lawyers Kenya has ever had.
