After winning election to the Senate, Wetangula was selected to serve as Minority Leader of the Coalition for Reforms and Democracy. The Bungoma High Court nullified his election on 30 September 2013 and the Speaker of the Senate declared the seat vacant on 16 October 2013. In a by-election held on 19 December 2013, Ford Kenya candidate Wetangula recaptured his Bungoma senatorial seat with a landslide win after garnering 149,458 votes against his main contender Musikari Kombo, who got about a half of the votes.
Kombo, who was vying on a New Ford Kenya ticket, came second with 81,016 votes followed by independent candidate David Makali and Labour Party of Kenya candidate Bifwoli Wakoli at a distant third and fourth place respectively. Makali secured 2,155 votes while Wakoli garnered 1,899 votes from a total of 942 polling stations, with a 57 percent voter turnout.
