I'm Wolf Flitzer, you're in the situation room. First up tonight to voting in Michigan where polls start closing in just two hours a big test for both

former President Donald Trump and President Biden in this key swing state for

And for Biden, will tonight's uncommitted vote,

as it's called especially from Michigan's large Arab American community

means similar general election trouble for him.
