I did a quick lookup of the quote you posted. Except for facebook and insta reposts, I found nothing. otoh, from yesterday's news:

President Netumbo Nandi-Ndaitwah has slammed circulating claims that Namibia is planning to deport 500 American citizens, calling the allegations false and urging the public to be vigilant of fake social media posts.

A press release issued by the Presidency on Wednesday said it has noted with concern the circulation of social media posts and online articles alleging that Nandi-Ndaitwah ordered the deportation of the American nationals on the grounds of visa reciprocity.

The statement pointed out that various social media accounts circulated this fabrication attributed to the president. “These posts feature fabricated quotes and images containing misinformation and disinformation intended to tarnish the image of the president, the Namibian government and to create potential diplomatic embarrassment,” it read.
