Mr Robertson, 84, remains an influential figure within conservative Christian circles in the United States.
He sought the Republican Party’s presidential nomination in 1988 and finished second, ahead of the elder George Bush in the initial contest that year. Mr Robertson’s vote totals dwindled, however, as the Republican primary process continued.
On his Thursday show, Mr Robertson further cautioned about the risks of contracting diseases from mosquito bites in Africa.
“The sanitation isn’t what it ought to be,” he added. “You drink the water, it’s not sterilised, you can get intestinal bugs.”
The gaffe-prone preacher is famous for making controversial statements which have had great ramifications on international relations.
His remarks in 2005 urging America to “take out” Hugo Chavez, the erstwhile Venezuelan dictator, were taken to mean that he meant for Chavez to be assassinated.
In his defence, he said that his remark could have meant anything.
CBN has since edited out the remarks from the official video uploaded on their site but the clip remains available on the internet.
