WASHINGTON — President Trump and his advisers have resisted calls from congressional Democrats and a growing number of governors to use a federal law that would mobilize industry and provide badly needed resources against the coronavirus spread, days after the president said he would consider using that authority.
Mr. Trump has given conflicting signals about the Defense Production Act since he first said on Wednesday that he was prepared to invoke the law, which was passed by Congress at the outset of the Korean War and grants presidents extraordinary powers to force American industries to ensure the availability of critical equipment.
The next day, he suggested that obtaining medical equipment should be up to individual governors because “we’re not a shipping clerk.” But on Friday, he reversed himself, asserting that he had used the law to spur the production of “millions of masks,” without offering evidence or specifics about who was manufacturing them or when they would reach health workers.
And Senator Chuck Schumer of New York, the Democratic leader, said that he was left with the impression after talking with Mr. Trump that he had decided to move to put the act into effect. He said “a commitment on the phone was a good start,” but that the president now needed to push the government “to move full steam ahead.”
But Mr. Trump’s confusing statements played out in the middle of a growing health crisis that within days has abruptly and indefinitely altered the course of American life.
With the number of coronavirus cases in the United States surging above 17,000 — over 40 percent of those concentrated in New York — front-line health care workers have reported a dire shortage of masks, surgical gowns and eye gear to protect them from the virus. State lawmakers have also implored the president to help them get the supplies they need.
Business leaders have said invoking the defense law is not necessary. During his appearance with the members of his coronavirus task force on Friday, Mr. Trump supported that idea and said that private companies, including General Motors, had volunteered to produce supplies without any prompting from the government.
“We are literally being besieged in a beautiful way by companies that want to do the work and help our country,” Mr. Trump said. “We have not had a problem with that at all.”
Some of the president’s advisers have privately said that they share the longstanding opposition of conservatives to government intervention and oppose using the law, and the president again signaled his own ambivalence about it.
