The rightwing populist has often defied local guidelines to wear a mask in public, even
after a judge ordered him to do so in late June.
Over the weekend, Bolsonaro attended several events and was in close contact with the US ambassador to Brazil during 4 July celebrations.
The US embassy in Brasilia said via Twitter that Todd Chapman, the ambassador, had lunch with Bolsonaro, five ministers and Bolsonaro’s son, Eduardo, who is a federal congressman. The ambassador had no symptoms, but would undergo testing and was “taking precautions”, the embassy said.
A photo posted on Twitter by Brazil’s foreign minister, Ernesto Araújo, shows Bolsonaro, Chapman and others sitting around a table, not wearing masks.
