President Donald Trump laid out new guidelines on Thursday for U.S. states to emerge from a coronavirus shutdown in a staggered, three-stage approach meant to revive the U.S. economy even as the country continues to fight the pandemic. The recommendations call on states to show a “downward trajectory” of COVID-19 cases or positive tests for the disease over 14 days before proceeding with the plan, which gradually loosens restrictions on businesses that have been shuttered to blunt the spread of the virus.
