New Week Brings New Challenges for White House Associated Press WASHINGTON - The Trump administration's leading health experts on safely dealing with the novel coronavirus will be testifying in a Senate hearing by a videoconference this week after three of them and the committee's chairman were exposed to people who tested positive for COVID-19. Adding to a string of potentially awkward moments for President Donald Trump, Vice President Mike Pence himself self-isolated for the weekend after a staff member tested positive for COVID-19. Pence leads Trump's coronavirus task force. The images of top administration officials taking such precautions come as states seek to loosen economic restrictions put in place to mitigate the virus' spread. In the Senate, a staff member for the office of Sen. Lamar Alexander, R-Tenn., tested positive for COVID-19, leading Alexander to decide to preside over Tuesday's hearing by teleconference while self-quarantining at home in Tennessee for two weeks. As the health experts discuss the administration's response to the outbreak, lawyers for Trump will hope to persuade a Supreme Court with two of his appointees to keep his tax and other financial records from being turned over to lawmakers and a New York district attorney. The justices are hearing arguments by telephone in a pivotal legal fight that could affect the presidential campaign. Rulings against the president could result in the quick release of personal financial information that Trump has sought strenuously to keep private. On Thursday, a House panels hears from Dr. Rick A. Bright, former director of the Biomedical Advanced Research and Development Authority. Bright asserts that he was summarily removed from his job and reassigned to a lesser role because he resisted political pressure to allow widespread use of hydroxychloroquine, a malaria drug favored by Trump. Perhaps most important of all the week's developments, the administration and Congress will be watching how businesses and consumers react as states gradually loosen restrictions that were designed to slow the spread of the coronavirus. .
