Brazil’s President Jair Bolsonaro has undergone another test for Covid-19 after showing symptoms of the virus. Bolsonaro said an exam showed his lungs are “clean” and that he would test for the coronavirus again. “But everything is fine,” he told supporters as he arrived at the residential palace, according to a video broadcast on a YouTube channel. The presidential office confirmed Bolsonaro was tested Monday night at a Brasilia hospital and said results would be available on Tuesday.
