US President Donald Trump has declared a national emergency to help handle the growing outbreak of coronavirus.
The announcement was part of a raft of new measures Trump hopes can bring a roiling health crisis under control after a week of market seesaws and major disruptions to everyday life.
As he sought to project an air of competence, Trump denied there were missteps that some health experts say have aggravated the crisis.
The declaration - "two very big words", according to Mr Trump - allows the federal government to tap up to $50bn (£40bn) in emergency relief funds.
There are 1,701 confirmed cases of Covid-19 in the US, and 40 deaths.
Several US states have taken measures to stem the infections rate, including banning large gatherings, sporting events and closing schools.
