By late 2015, Khumalo was in office as Mayor of
Tlokwe Local Municipality in the North West. Pursuant to the
2016 local elections, he was elected as Mayor of
JB Marks Local Municipality (initially referred to as NW405), which was formed in a controversial merger of the Tlokwe and
Ventersdorp municipalities. The ANC Youth League in the region called for his resignation as early as March 2017, and he faced sizeable
service-delivery protests in August 2018, with hundreds of residents marching to demand his resignation and that of his senior management team, alleging that they were responsible for underperformance and even
embezzlement of funds. In October 2020, the
Hawks arrested Khumalo and a senior official on
fraud and theft charges. They were accused of having misappropriated about
R5 million in municipal funds, including a large contribution to the funeral of
Ndleleni Duma in 2018, apparently by falsifying invoices. On the instructions of the ANC, Khumalo stepped aside from the mayoral office on 12 May 2021; he was succeeded by Mapule Mataboge in July. == Personal life ==
