Vice President Mike Pence will be in Rochester today to tour Mayo Clinic facilities supporting COVID-19 research and treatment, and to meet with Mayo Clinic personnel. Minnesota Democratic Party leaders say Pence is trying to paper over the Trump administration’s failings and take credit for Governor Walz’s leadership. They say Trump and Pence broke their promise to provide adequate testing for Americans and personal protective equipment for health care workers. Meanwhile the White House yesterday unveiled what it terms a comprehensive effort to make enough COVID tests available for states to test at least 2.6 percent of their populations each month — and higher in hard-hit areas. The administration also released new guidelines for re-opening businesses.
