evidence: From the beginning of the coronavirus outbreak in the United States, President Donald Trump has projected a cavalier attitude towards mask-wearing, refusing to wear a mask in public and mocking others who do. Trump routinely appears without a mask as he carries on a high-risk campaign travel schedule of public rallies he sarcastically calls "peaceful protests" as he pushes to reopen the US economy to win re-election. [...] Refusing to wear a mask became a political statement for Trump supporters as early as June when the president held a large public rally in Tulsa, Oklahoma, with thousands of attendees who did not wear masks.
