Brazil’s President Jair Bolsonaro led thousands of motorcyclist supporters through the streets of Sao Paulo — and got hit with a fine for failure to wear a mask in violation of local pandemic restrictions.

The conservative president waved to the crowd from his motorcycle and later from atop a sound truck, where helmeted but largely maskless backers cheered and chanted as he insisted that masks were useless for those already vaccinated — an assertion disputed by most public health experts.

Sao Paulo’s state government press office said a fine — equivalent to about $110 — would be imposed for violation of a rule that has required masks in public places since May 2020. According to a survey by local authorities, 12,000 motorcycles participated in the pro-Bolsonaro event, AP reported.
