President Donald Trump is resisting calls to issue a national stay-at-home order to stem the spread of the new coronavirus. This is despite his administration’s projections that tens of thousands of Americans are likely to be killed by the disease. One by one, though, states are increasingly pushing shutdown orders of their own. On Wednesday alone, three more states — Florida, Nevada, and Pennsylvania — added or expanded their stay-at-home orders. The resistance to a more robust federal response comes even as Vice President Mike Pence says White House models for the coronavirus toll show the country on a trajectory akin to hard-hit Italy.
