Kamala Harris and Donald Trump both sought support from Arab American voters on Friday as they campaigned in Michigan, trying to lock down support in a battleground state that could decide the presidential race next month. Trump was expected to visit a new campaign office in Hamtramck, one of the nation's only Muslim-majority cities, and he will be joined there by Mayor Amer Ghalib, a Democrat who has endorsed him. Meanwhile, three city council members in the same town have endorsed Harris.

Michigan is one of three "blue wall" states that, along with Pennsylvania and Wisconsin, will help decide the election, and the diverse voting blocs are key to winning the state. "It's an election for president. It's not supposed to be a cake walk for anyone. There are very important issues at play," Harris said. David Plouffe, a top campaign adviser for Harris, said on Friday on CNN that he believed all of the swing states were still in play, but the key was zeroing in on voting blocs. "We're going to treat every cohort like they're a swing voter," he said.
