Seven Republican senators, including top figures like Sen. Chuck Grassley (Iowa) and former Senate Majority Leader Mitch McConnell (Ky.), are teaming up with Democrats to push a bill that would force Congress to approve President Trump’s hefty tariffs on trade partners.
Grassley, McConnell, and five other Republicans—Sens. Jerry Moran (Kan.), Lisa Murkowski (Alaska), Thom Tillis (N.C.), Todd Young (Ind.), and Susan Collins (Maine)—are backing the Trade Review Act of 2025. This new legislation aims to curb Trump’s ability to slap tariffs on countries without Congress having a say.
If passed, the bill would require Trump to notify Congress about any new or increased tariffs within 28 hours and explain why he’s imposing them. The administration would also have to assess how these tariffs might hurt American businesses and consumers.
The most significant change is that any new tariffs would expire after 60 days unless Congress approves them. Even before that, Congress could cancel the tariffs earlier by passing a resolution of disapproval.
Trump has already threatened to veto the bill. But Grassley, who is leading the effort, says it’s time for Congress to take back control of trade decisions.
“For too long, Congress has delegated its clear authority to regulate interstate and foreign commerce to the executive branch. I’m joining Sen. Cantwell to introduce this bill to reassert Congress’ constitutional role and ensure we have a say in trade policy,” Grassley said.
The proposal is modeled after the War Powers Resolution of 1973, which limits a president’s ability to take military action without congressional approval.
The Trump administration has strongly opposed the bill. A White House statement argues it would “severely constrain the president’s ability” to act on national emergencies or foreign threats, noting that the bill would require Congress to approve nearly every tariff increase.
Just last week, Trump announced tariffs on over 180 countries by invoking emergency powers under the International Emergency Economic Powers Act.
