US Chamber of Commerce weighing a lawsuit to block new Trump global tariffs

The U.S. Chamber of Commerce is weighing a potential lawsuit against the Trump administration in a bid to block a new round of global tariffs set to take effect Wednesday.

Pressured by major corporate members, the Chamber may argue that President Trump improperly used emergency powers under the International Emergency Economic Powers Act (IEEPA) to justify the measures.

Fearing retaliation, many businesses are reluctant to speak out directly and are instead pushing trade associations to take the lead.

A civil liberties group has already filed a separate legal challenge on similar grounds. (Trump sued over China tariffs: legal challenge alleges abuse of emergency powers)

While the Chamber typically aligns with Republican administrations, it has occasionally broken ranks—including a previous lawsuit against Trump over immigration policy—highlighting growing corporate resistance to the administration’s aggressive trade agenda.
