A growing number of White House staff and senior Republicans have tested positive for Covid-19 since US President Donald Trump revealed last week that he had contracted the respiratory disease.
The infections have interrupted campaigning for the presidential election on 3 November, rattled financial markets and slowed the work of Congress, with the Senate vowing to delay any votes now that three members of the Republican majority have tested positive.
