President Donald Trump is scheduled to rally Republicans in eastern Michigan on Sunday, the day after former President Barack Obama campaigned for Democrats in the state. The visits underscore Michigan's competitive role in the upcoming midterm elections. The state is hosting a key US Senate contest between Republican Mike Rogers and Democrat Abdul El-Sayed, which could determine control of the chamber. Trump has repeatedly attacked El-Sayed, questioning his allegiance to the US and his ties to the Muslim Brotherhood, allegations El-Sayed denies. Obama, speaking at a rally in Detroit, framed these attacks as attempts to make El-Sayed appear less patriotic, drawing parallels to his own experience with similar claims. Trump's rally in Port Huron will also address the US-Canada tariff dispute, which has impacted the auto industry.
