US president Donald Trump told a female reporter to keep her voice down and to ‘relax’ when she asked about what his administration had done to prepare for the coronavirus in February. CBS reporter Weijia Jiang asked Trump why he waited so long ‘to warn people the virus was spreading like wildfire’ in February ‘instead of holding rallies with thousands of people’? An irritated Trump touted his China travel ban as proof he acted fast. Jiang persisted with her point and said: ‘When you issued the ban, the virus was already here,’ to which Trump said: ‘Do your research.’
