The US coronavirus crisis took a sharp political turn on Friday as President Donald Trump lashed out at four Democratic governors over their handling of the pandemic after having conceded that states bear ultimate control of restrictions to contain the outbreak. The Republican president targeted three swing states critical to his re-election bid – Michigan, Minnesota and Virginia – where his conservative loyalists have mounted pressure campaigns challenging those governors’ stay-at-home orders. Amplifying a theme that his supporters have trumpeted this week in street protests at the state capitals of Lansing, St. Paul, and Richmond, Trump issued a series of matching Twitter posts touting the slogans: “LIBERATE MICHIGAN!” “LIBERATE MINNESOTA!” and “LIBERATE VIRGINIA!” Michigan has become a particular focus of agitation to relax social-distancing rules that rank among the strictest in the nation after Governor Gretchen Whitmer, widely seen as a potential running mate for presumed Democratic presidential candidate Joe Biden, extended them through the end of April. Protesters defying the restrictions from the steps of the state Capitol on Wednesday shouted “lock her up,” a chant that was a staple of Trump’s campaign rallies and originally referred to his 2016 Democratic rival, Hillary Clinton. ‘WHEN IT’S SAFE’ Whitmer said on Friday she was hopeful her state, which suffered one of the country’s fastest-growing coronavirus infection rates, can begin to restart parts of its economy on May 1. But she urged doing so cautiously to avoid reigniting the outbreak just as it was being brought to heel. Responding to Trump’s critique later in the day, Whitmer said Michigan will re-engage its economy when it’s safe, adding: “The last thing I want to do is to have a second wave here.”
