WASHINGTON (Reuters) - President Donald Trump on Wednesday paused for 90 days many tariffs but is not halting 25% tariffs on automotive imports and looming tariffs on auto parts, drawing criticism from Michigan business and auto groups.

The Detroit Regional Chamber and MichiganAuto called on Trump to protect the automotive industry's complex international supply chain framework from harmful fragmentation that weakens its global competitiveness.

"Michigan's signature industry and the supply chains and employees that sustain it will continue to endure the uncertainty and disruption of these fluctuating trade policies," they said in a statement.
