Jean-Pierre, 44, added that she has “mild symptoms” and will work from home until she has completed her five-day isolation period and a negative Covid-19 test. He had traveled to Air Force One with the President and his team during his four-day tenure in Europe to rally the world’s democracies and announce more action against Russia over its invasion of Ukraine. Ahead of the trip, White House spokeswoman Jen Psaki said she tested positive for Covid-19 for the second time, also showing mild symptoms. And earlier in March, second-in-command Doug Emhoff tested positive for the virus, marking the first known Covid-19 case between the first or second family since Biden and Vice President Kamala Harris took office in January 2021. The last publicly known negative test of the President Covid-19 was on Friday, the day he left Brussels for Warsaw. Inside the White House last month, according to federal public health guidelines, officials and visitors were not required to wear masks or social distance. Visitors are expected to take a Covid-19 test before attending official White House events. Covid-19 cases in Washington, DC, have declined since their peak in early January, when the country was facing a wave of Omicron-type cases.
