Michigan Gov. Gretchen Whitmer warns of worsening auto industry under Trump's tariff strategy

DETROIT (AP) — Michigan Gov. Gretchen Whitmer offered a contrasting view of manufacturing in Detroit Thursday, two days after President Donald Trump defended his tariff strategy in the Motor City.

Whitmer, a term-limited Democrat who is in her last year as governor, said in a speech at the Detroit Auto Show that the administration's tariff strategy has hurt American auto manufacturing and is benefiting Chinese competitors. It's a message she has repeated over the past year as economic uncertainty has rippled across the automobile sector.

“This will only get worse without a serious shift in national policy,” Whitmer said.

Her remarks followed Trump's speech defending his economic policy Tuesday in Detroit, a major hub of automobile manufacturing. He also toured the factory floor of a Ford plant in Dearborn.

“All U.S. automakers are doing great,” Trump said.

Whitmer offered a differing picture of the impact, saying that American manufacturing has contracted for months leading to job loss and production cuts. She has remained firmly opposed to Trump’s tariff strategy since last year, especially as her state partners closely with Canadian business. Automobile parts often cross the U.S.-Canadian border several times in the assembly process.

“America stands more alone than she has in decades,” Whitmer said. “And perhaps no industry has seen more change and been more impacted than our auto industry.”

The White House did not immediately respond to a request for comment on Whitmer's speech.

Whitmer has kept a more cordial relationship with Trump in his second term compared to his first. The relationship included a few White House visits last year. Long considered a possible Democratic candidate for president, Whitmer’s strategy is notably different than other potential 2028 names who have take more public, combative approaches to Trump, including California Gov. Gavin Newsom and Illinois Gov. J.B. Pritzker.

In her address, her first of the year, Whitmer said every time she has met with Trump this past year, she has told him that hurting the U.S.-Canadian relationship only helps Chinese competition.

Trump changed his tune when it comes to automobiles in the last year. He originally announced a 25% tariff on automobiles and parts only to later relax the policy as domestic manufactures sought relief from the threat of rising production costs.

On his tour in the Detroit area, Trump suggested the United States-Mexico-Canada Agreement, a major trade agreement he negotiated in his first term, was irrelevant, although he provided few other details The UMCA is up for review this year.

Whitmer defended the trade agreement in her speech.

“When we fight our neighbors, however, China wins,” she said.
