Here's a quick rundown about why Michigan is so vulnerable to the tariffs Trump ordered Tuesday on Canada and Mexico (and China).

Jose Guadalupe Jaimes dropped off his son at a middle school in Trenton, his children said. Moments later, the immigrant father driving a work van was approached by three vehicles with their lights flashing.

Facing supply chain chaos and higher costs for consumers, Michigan auto leaders convinced President Donald Trump to give them a temporary exemption to 25% tariffs on imports from Canada and Mexico.

Trump's tariff moves have caused a gaping wound in the decades-old North American trade partnership, have also caused the stock market to sink and alarmed U.S. consumers.
