Trump and his backers have filed challenges the past two days in Michigan, Wisconsin and Pennsylvania, which were critical to Trump’s surprise victory last month because they punctured the so-called blue wall of states expected to carry Democrat Hillary Clinton to victory. Trump narrowly won the trio of states. Michigan Attorney General Bill Schuette (R) on Friday tweeted that Stein’s request was “an expensive & a risky threat” as he announced he had filed an emergency motion with the Michigan Supreme Court to stop it. Stein, who has raised millions of dollars from supporters to help pay for the costly recount efforts, blasted back at what she called “a politically motivated attempt by Bill Schuette to side with Donald Trump in opposition to a fair and accountable voting system.’’
