Michigan primary live updates as polls start to close in state

Polls have closed in parts of Michigan, where both Democrats and Republicans are voting in the state's primary. Polls in parts of the Upper Peninsula will be open until 9 p.m. ET.

Former President Donald Trump and former U.N. Ambassador Nikki Haley are continuing to duke it out for the Republican nomination. On Saturday, Trump defeated Haley by 30 points in her home state of South Carolina, but Haley has vowed to continue in the race through Super Tuesday on March 5. 

While President Biden doesn't have a major challenger in the Democratic race, Tuesday's election may not be a blowout for him due to a movement led by Arab and Muslim American voters in the state to vote "uncommitted" in the primary as a protest of his policy toward Israel. If "uncommitted" receives more than 15% of the vote, then unpledged delegates would be awarded.
