Air Force One Exposure Puts a Hold on Biden Campaign Coverage for VOA Reporter Steve Herman WHITE HOUSE - The day before President Donald Trump tested positive for COVID-19, he flew to Minnesota on Air Force One with senior staff, as well as pool reporters, including VOA's White House bureau chief Steve Herman. The next day Herman traveled to Wilmington to prepare to cover a Joe Biden rally, the only reporter who attempted to switch between the Trump and Biden campaigns this week. He describes the experience following the president's positive coronavirus test. At the White House on Wednesday morning, a member of the medical office swabbed my nose to collect a sample for the routine COVID-19 rapid test administered daily to all members of the protective pool of reporters covering the president's activities. It was a brief and painless procedure. I had undergone it more than a dozen times in recent months -- always with the same "negative" result. That has also been the case for my colleagues on the White House beat, Patsy Widakuswara and Carolyn Presutti, with whom I alternate campaign coverage when it is VOA's turn in the rotation among radio networks. As the day's designated radio pooler for the Minnesota round trip on Air Force One, I was responsible for ensuring that all the networks would have broadcast quality audio whenever the president spoke -- from the time we left Joint Base Andrews in Maryland to our post-midnight return on the same military tarmac. The president's first stop in Minnesota, known as "the Land of 10,000 Lakes," was a massive multimillion-dollar estate on the shores of Lake Minnetonka. At a fundraiser at the home of wealthy Republican Party donor Martin Davis, during which the accompanying media waited outside in our vans, Trump mingled with an unannounced number of guests. Thus, we were not able to observe if the participants were wearing masks or engaged in social distancing. Duluth rally Such recommended precautions were certainly not seen at the president's next stop in Duluth, where an airport rally was held. Thousands of enthusiastic supporters turned out -- crammed in bleachers, on the tarmac and in the hangar. Only about a fifth of the crowd wore any type of face covering. Trump spoke for 45 minutes. His normal rally remarks usually stretch beyond an hour. This, I noted at the time, was unusual. But it was chilly and windy on the north shore of Lake Superior on the last day of September. .
