Trump Orders US Flags at Half-Staff for COVID-19 Victims VOA News U.S. President Donald Trump has ordered flags on all federal buildings and monuments lowed to half-staff for the next three days in memory of all Americans who have lost their lives to the coronavirus. He made the announcement late Thursday on Twitter at the same time he said the lowered flags Monday will also honor servicemen and women "who have made the ultimate sacrifice for our nation" as the country marks Memorial Day. Meanwhile, Michigan's attorney general said Trump may not be invited back to the state if he refuses to wear a face mask in public. Trump on Thursday visited a Ford auto factory near Detroit that has been converted into a plant to build ventilators. All of the Ford executives who were showing Trump around the plant were wearing face masks. But Trump, as he has always done, refused to wear one. Michigan Attorney General Dana Nessel said it isn't just Ford Motors' policy that all visitors to its plants wear a mask -- it is also state law. "He's going to be asked not to return to any enclosed facilities inside our state '¦ we're going to have to take action" against any company that allows it in the future," Nessel said. When asked if Trump was told it was not acceptable to not wear a mask in the plant, Ford Executive Chairman Bill Ford said, "It's up to him." Trump claimed he did wear a mask out of view of reporters because he said he did not want to give the media the pleasure of seeing it. The president has reportedly told White House aides that he does not want to wear a mask in public because he thinks it makes him look weak. .
