President Donald Trump announced Sunday that he's extending his administration's guidelines on social distancing during the COVID-19 outbreak until April 30. The move marks a significant change for the president, who said last week that he wanted to see much of the country return to normal by Easter, April 12, despite warnings from top health experts that easing guidelines could cause widespread death and economic damage.

Meanwhile, in an interview with "TODAY" on Monday morning, White House coronavirus response coordinator Dr. Deborah Birx said she's "very worried" about every city in the U.S., saying 100,000 to 200,000 American deaths would be the outcome of a response that works "almost perfectly," according to projections.

Birx's stark message comes after a weekend where the governors of Michigan and Louisiana warned of a lack of resources to respond to the crisis and said that shortages of ventilators and protective equipment could overwhelm hospitals as soon as this week.

The global death toll is now nearly 35,000, and there are more than 140,000 confirmed cases in the U.S., according to Johns Hopkins University.
