Early Life
Richard Momoima Onyonka was born on January 1, 1962, in Kisii County, in what was then a year before Kenya gained independence from British colonial rule.
He comes from the Kitutu Chache South constituency within Kisii County and is a member of the Abagusii (Kisii) ethnic community one of Kenya’s most intellectually vibrant and politically assertive communities.
Richard’s family background is both complex and fascinating. He is publicly associated with the legacy of the late Dr. Zachary Onyonka, the celebrated Kenyan Cabinet Minister and first Kisii man to earn a PhD a giant of Kenyan post-independence politics who served in various ministries under both Presidents Jomo Kenyatta and Daniel Arap Moi. Richard grew up bearing the Onyonka surname and was long considered Dr. Zachary’s son.
However, in 2026, following the death of his biological mother, Mama Teresa Nyaboke Omoke, the question arose publicly about why he carries the Onyonka name and not the Omoke surname of his biological father. The senator traces his upbringing to two villages and two father figures a biological father and a foster or adoptive one a background that shaped his identity and sense of community belonging from an early age.
Despite the complexities of his family background, the political influence of the Onyonka household was a constant feature of Richard’s upbringing.
Growing up in the shadow of one of Kenya’s most prominent Cabinet Ministers exposed him to governance, public service, and national affairs from childhood. It also meant, however, that when he later found himself on the wrong side of the Moi government’s authority, it created a painful personal conflict as Dr. Zachary Onyonka was a close ally of the very president whose government was arresting Richard.
As a young man, Richard was also passionate about sports, particularly football. He played as a goalkeeper during his school years a position that, in hindsight, mirrors the defensive and watchful role he has often assumed in politics.
Education
Richard Onyonka began his primary education at Otamba Primary School and later attended St. Mary’s Mosocho Primary School, both in Kisii County. For his O-Level secondary education, he enrolled at the prestigious Kisii High School, one of Kenya’s top national schools. He then transitioned to St. Mary’s School Yala for his A-Level studies.
In 1980, he gained admission to the University of Nairobi, where he pursued a Bachelor’s degree in Commerce a programme that covered economics, business, and international trade, subjects he would later apply throughout his political career.
He graduated from the university in 1985 with his undergraduate degree. During his campus years, he reportedly loved the International Trade unit and had an aversion to statistics.
He later earned a Master’s degree in Economics and Public Management from a university in the United States in 1987, a qualification that substantially deepened his expertise in fiscal policy, public administration, and governance.
His university years were not without drama. In 1982, while a student at the University of Nairobi, Richard was among approximately 152 to 156 students arrested in connection with the Kenya Air Force’s failed coup attempt against President Daniel arap Moi’s government on August 1, 1982. Musalia Mudavadi, who would later become a key figure in Kenyan opposition politics, was also among those arrested.
The High Court subsequently ordered the release of the group on grounds of “nolle prosequi” a legal decision not to prosecute just in time for their university examinations. Richard has since recalled this period as one that sharpened his political instincts, broadened his worldview, and planted the seeds of his eventual entry into formal politics.
Career
Richard Onyonka’s political journey is one of persistence, reinvention, and grassroots endurance. Before entering elective politics, he served in the Ministry of Foreign Affairs as an assistant minister during the administration of President Mwai Kibaki a role that leveraged his academic background in economics and international trade.
His first attempt to win a parliamentary seat was unsuccessful. In the 2002 general elections, he contested the Kitutu Chache constituency seat but lost to Jimmy Angwenyi. Undeterred, he rebuilt his grassroots presence and tried again in 2007.
This time, running on a People’s Democratic Party (PDP) ticket, he won successfully capturing the Kitutu Chache constituency seat in the National Assembly of Kenya. His election marked the beginning of what would become one of the most durable parliamentary careers in the history of Kisii County politics.
Between 2008 and 2013, he served as an Assistant Minister for Foreign Affairs under President Kibaki, a role consistent with his academic expertise and family tradition in external affairs his father Dr. Zachary had also served as Foreign Affairs Minister. Onyonka was recognized for his articulate contributions to parliamentary debates and his willingness to take on powerful figures within the government and opposition alike.
Following the 2010 constitutional changes that introduced constituency delimitation, the former Kitutu Chache constituency was split.
In the 2013 elections, Richard contested and won the newly created Kitutu Chache South constituency seat under the Orange Democratic Movement (ODM) banner.
He was re-elected to the same seat in 2017, this time on a Ford Kenya Party ticket, defeating the Jubilee Party candidate Anthony Kibagendi by a significant margin. His back-to-back victories in 2013 and 2017 consolidated his position as the dominant political figure in Kitutu Chache South.
During the 2013–2017 parliamentary term, Onyonka served as a member of the Departmental Committee on Defence and Foreign Relations, a fitting role given his background and family legacy in Kenya’s foreign policy sphere.
He was consistently regarded as one of the more intellectually rigorous members of parliament, preferring data-backed arguments and constitutional principles to populist rhetoric.
In the 2022 general elections, rather than defending his National Assembly seat, Onyonka made the strategic decision to contest the Kisii County Senate seat under the ODM ticket.
He won convincingly, transitioning from the National Assembly to the Senate a move that expanded the geographic scope of his political mandate from a single constituency to the entire Kisii County.
As Senator, he has been vocal on issues of fiscal accountability, devolution, social justice, and good governance. He has also been notably outspoken on issues relating to the rights of county governments and in holding the national executive accountable.
Controversies
Richard Onyonka’s long career has not been without its share of controversies. In 2011, he was questioned by the Kenya Anti-Corruption Commission (KACC) over allegations of misappropriating Ksh 137 million from his Constituency Development Fund (CDF).
Reports in 2014 indicated that the Director of Public Prosecutions had ordered that he be charged in connection with graft and non-remittance of taxes involving these funds. The matter generated significant public debate about accountability in the management of public resources at the constituency level.
In January 2022, Onyonka was arrested and investigated following allegations of hate speech and incitement connected to remarks he made during a public rally in Kisii.
A human rights activist filed a court application attempting to block the Director of Public Prosecutions from charging him, arguing that the directive to investigate was itself unlawful. The case attracted wide attention and reflected the charged political atmosphere in the run-up to Kenya’s August 2022 general elections.
In December 2021, Onyonka made national headlines when he was allegedly poisoned while attending a political event in Kisii County. Reports indicated that he began bleeding from his mouth after drinking from a water bottle passed to him by an unidentified individual.
He was rushed to hospital and later discharged after recovering. Police opened an investigation into the incident, which sent shockwaves through Kenya’s political community and prompted discussions about the safety of politicians in the competitive Kisii political landscape.
In 2026, dramatic scenes unfolded at a political rally in Nakuru County when a snake reportedly invaded the VIP tent just as Senator Onyonka had begun publicly questioning President William Ruto on corruption and land matters.
The incident, which occurred during a gathering to popularize former CS Fred Matiang’i’s 2027 presidential bid, became one of the more unusual political theater moments of recent Kenyan political life.
Social Media
Senator Richard Onyonka maintains a public profile and engages in national discourse through social media. He is active on X (formerly Twitter), where he regularly comments on Senate proceedings, national governance, and economic matters.
He has also been at the centre of multiple viral social media moments from the Nakuru snake incident to his revelation about his family life in May 2026. His parliamentary addresses are frequently shared online, particularly when he takes strong positions on constitutional matters or challenges executive overreach.
Personal Life
For much of his political career, Richard Onyonka kept the details of his personal life strictly private. In May 2026, however, following the death of his mother Mama Teresa Nyaboke Omoke (who passed away on April 29, 2026, at the age of 81 while receiving treatment in Nairobi), the senator made a series of frank public disclosures about his family life during condolence visits at his home.
Onyonka publicly confirmed that he is a polygamous man and the father of 12 children with different women. He revealed that his wives include former IEBC (Independent Electoral and Boundaries Commission) Commissioner Roselyn Akombe a revelation that shocked and fascinated Kenya’s public and political circles in equal measure, given that neither party had previously acknowledged the relationship.
Onyonka stated that Akombe had played a deeply personal role in his family, including caring for his late mother and facilitating her medical treatment in the United States. He also identified Wanjiru as among his wives, alongside at least three others.
Roselyn Kwamboka Akombe, born on November 21, 1976, in Nyamira County, is a political economist and former IEBC Commissioner who gained international prominence in 2017 when she resigned from the electoral body ahead of Kenya’s repeat presidential election, citing concerns about the integrity of the process and her personal safety.
She subsequently worked with the United Nations in peacebuilding and governance roles. Her revelation as Senator Onyonka’s wife in May 2026 added another layer of public intrigue to both their careers.
Regarding his own parentage, Richard has traced his upbringing to two fathers the biological and the foster a detail that gained renewed public attention following the death of his biological mother, Teresa Nyaboke Omoke, in April 2026. The senator carries the Onyonka name, associated with the legacy of his foster/political father figure Dr. Zachary Onyonka, rather than the Omoke surname of his biological father.
Richard has in the past described himself as a proud polygamist, saying that he has embraced his family structure openly and intends to formally introduce all his children to the public. He is based between Kisii County and Nairobi.
His Father: The Legacy of Dr. Zachary Onyonka
Any biography of Richard Onyonka would be incomplete without acknowledging the towering influence of the late Dr. Zachary Onyonka (1939–1996), the prominent Kenyan Cabinet Minister and economist who was the first Kisii man to earn a PhD. Dr. Zachary served in Parliament from 1969 until his death in 1996, representing the Kitutu West and later Kitutu Chache constituencies.
He served in numerous ministries including Economic Planning, Foreign Affairs, Health, Housing, Information and Broadcasting, and Science and Technology under both Presidents Jomo Kenyatta and Daniel arap Moi. He died of a stroke on October 22, 1996, while serving as Minister for Research, Technical Training and Technology.
