President Donald Trump has warned that the US pandemic will probably “get worse before it gets better”, as he revived his Covid-19 briefings. Mr Trump also asked all Americans to wear face coverings, saying they’ll have an effect and show patriotism.

He was not wearing a mask at the briefing, but has previously downplayed such personal protective equipment. The president’s aides have reportedly asked him to adopt a new tone as virus caseloads spike across the US.

In his first White House covid briefing for months on Tuesday, a more scripted president echoed what public health officials on his pandemic task force have been saying as he warned that it will probably unfortunately get worse before it gets better.
