Home Affairs Minister Malusi Gigaba visited the Guptas for "social cohesion reasons", but denies they had any sway over him.
"During my tenure, I, at no stage, assisted the Gupta family, or any other private interest group, to capture the state," Gigaba told the Portfolio Committee on Home Affairs on Tuesday night.
The committee is holding an inquiry into four members of the Gupta family's early naturalisation. The committee started listening to testimony at about 10:00. Gigaba appeared before the committee shortly after 22:00.
Gigaba said having studied a report of the testimony the committee previously heard: "I am satisfied that it does not implicate me in any wrongdoing.
"It is unfortunate that this issue of the naturalisation of one family, has been used to cast negative aspersions on me," he said.
