Trump Administration Officials Discuss Coronavirus on Sunday Talk Shows

House Speaker Nancy Pelosi, in an appearance on the ABC program “This Week,” said that she supported a federal mandate that all Americans must wear masks. “Definitely long overdue for that,” said Ms. Pelosi, a Democrat from California. She urged Mr. Trump to start wearing one in public, saying: “Real men wear masks. Be an example to the country.”

Gov. Jay Inslee of Washington expressed frustration at the president’s unwillingness to wear masks or to do more to encourage his supporters to wear them. “Instead of tweeting the other day about the importance of masks, he tweeted about monuments,” he said on “Face the Nation.” “We need a president who will care more about living Americans and less about dead confederates.”

Mr. Azar, asked why the administration is seeking to dismantle the Affordable Care Act, which could take insurance away from 24 million Americans, said the administration would ensure that health care for virus patients would be free.

“If you are uninsured, it will be covered by us,” Mr. Azar said. But he did not disclose details of any replacement plan that would guarantee protections for people with pre-existing conditions so that they would not face higher costs for insurance.

Gov. Asa Hutchinson, Republican of Arkansas, said that a quarantine requirement in New York, New Jersey and Connecticut for travelers from states with growing infections was “understandable,” but argued that travel restrictions could stand in the way of economic recovery.

“We had the same order in Arkansas, that travelers from New York had to quarantine. We’ve lifted all of those now because this virus has become like a fog going across the United States, sometimes slowly, sometimes rapidly,” he said, as his own state’s reopening was paused amid a rise in cases.
