President Trump announced new coronavirus guidelines for at least the next 15 days, including that Americans should avoid groups of more than 10 people.
In a briefing at the White House on Monday, he also urged people to avoid discretionary travel and going out to bars, restaurants and food courts. He recommended that schools close.
The stricter guidelines marked a shift for the president, who has repeatedly stated that the virus is under control.
"Whatever it takes, we're doing," Trump said.
