Mkhwebane is playing at politics here. How did she even agree to investigate this, first Zille may have tweeted something stupid but that is her right to free speech and second, how can Mkhwebane agree to investigate something like that to begin with, she should have sent it back as not within her purview. The PP keeps harping on about lack of resources to investigate real issues with real impact on the public yet here she goes and investigates a sideshow. Many of our politicians make stupid and even dangerous utterances on a daily basis. What the PP is doing here is playing to the ANC's gallery to try and gain sympathy against the potential review into her fitness to hold office.
