Rehman, who is also considering suing the official, said that because the Gupta family had made the headlines for the wrong reasons, it had unfairly impacted upon how an entire community was viewed.
The Gupta family, which has close ties to South African President Jacob Zuma, made global headlines when a plane, chartered by them, carrying around 200 guests from India, landed at Waterkloof Air Force base without proper authorisation last week, triggering widespread criticism.
The guests had arrived to attend the wedding of billionaire Atul Gupta's daughter.
Reacting over the incident, Gupta said his family was "really saddened by the racism and xenophobia driving the current debates".
