John Harun Mwau

Mwau vied for senatorial position for Makueni in 2013 Election. He was defeated by Mutula Kilonzo

Mutula Kilonzo Jnr a son of former senator Mutula Kilonzo of Wiper Democratic Party won 163,232 votes to win the Makueni Senate seat in the 2013 by-election. Mwau therefore has lost senatorial election to father and son in a span of 5 month.

Makueni by-election, the first after the 4 March 2013 general election, was occasioned by the death of Mutula Kilonzo on 27 April 2013. The voter turnout was 60.4%.

In 2011, the United States designated Harun Mwau, who was MP at the time, on a list of seven “narcotic kingpins”. Under this legislation, American assets are frozen, and access to the American financial system is denied. Harun Mwau has been cited as one of "the more powerful and active narcotics traffickers in the region" by the Director of the Office of Foreign Assets Control of the US Department of Treasury. Harun Mwau has been denying the charges and says that the United States government is attempting to seize his businesses, which are estimated to be worth $750 million.

In 2005, Harun Mwau sued the Nation Media group for an alleged defamatory article which implicated him in a tax evasion scandal. The same year, he filed four suits against the senior executives and editors of Kenya's leading media houses to permanently bar the media from publishing reports linking him to drug trafficking. In 2011, Harun Mwau sued the United States Ambassador Michael Ranneberger for associating him to narcotic drug trafficking.  In 2013, he sued a student over a Facebook post linking him to the murder of Internal Security minister, George Saitoti. In 2014, he sued the author of a report from the International Peace Institute, where his designation by the US government as a foreign narcotics kingpin was mentioned. In 2017, he sued the authors of two blog posts which link him to a businessman believed to be close to Colombia's drug cartels. The same year, he sued the Kenyan Independent Electoral and Boundaries Commission for "intending to conduct a fresh presidential election without nominations".

Harun Mwau is the founding chairman Party of Independent Candidates of Kenya (PICK) and ran as a Presidential Candidate in the 1992 Kenyan general election. Mwau polled 10,449 votes and later petitioned the High Court to declare him the only validly nominated candidate, as other candidates did not present the list of supporters nominating them using the correct paper size. The case was dismissed by the High Court.

Prior to his career as a politician, he was a sports shooter and competed at the 1968 Summer Olympics and the 1972 Summer Olympics.
