Michigan Gov. Gretchen Whitmer is worried President Trump’s campaign events will contribute to the spread of COVID-19 but isn’t too worried about Democratic nominee Joe Biden’s campaign events.

Speaking to Anderson Cooper on Tuesday evening, Whitmer said Trump’s visit this week is “distressing.” She didn’t express the same level of concern about Biden’s Wednesday visit, saying that the campaign “is scrupulously following the science” and that “they want to keep their supporters and the general public safe.”
