David Harris, Jr. is apparently popular in certain circles as a black man who supports President Trump, though I hadn’t heard of him until he made a ruckus on an American Airlines flight – refusing to wear a mask, and advising his followers that only N95 masks are prophylactic, which isn’t supported by the balance of evidence at this point.
Apparently Mr. Harris held up a flight departure on Saturday when he boarded without a mask on, and passengers complained. He reports that he “declared [to] have a medical reason to not wear a mask.”
