The Trump White House has threatened to veto a bipartisan Senate bill that would check President Trump’s authority to impose new tariffs or increase tariffs by requiring Congress to approve them within 60 days. In a statement of administrative policy circulated to Senate offices Monday , the Trump administration informed lawmakers that it “strongly opposes” the Trade Review Act of 2025. The administration argued the legislation would “severely constrain the president’s ability to use authorities long recognized by Congress and upheld by the courts to respond to national emergencies and foreign threats.” “If S. 1272 were presented to the President, he would veto the bill,” the White House budget office warned. The legislation was introduced last week by Sen. Chuck Grassley (R-Iowa), the chair of the Judiciary Committee, and Sen. Maria Cantwell (D-Wash.), the ranking member of the Commerce Committee. It would require the president to notify Congress within 48 hours of the imposition of a new tariff or the increase of a tariff and provide “an explanation of the reasoning for imposing or increasing the duty” and an assessment of the potential impact of imposing or increasing a duty on U.S. businesses and consumers. And it would require that tariffs expire after 60 days unless Congress passes a joint resolution of approval. Congress could cancel new tariffs or increase tariffs by passing a joint resolution of disapproval. “For too long, Congress has delegated its clear authority to regulate interstate and foreign commerce to the executive branch. Building on my previous efforts as Finance Committee Chairman, I’m joining Sen. Cantwell to introduce the bipartisan Trade Review Act of 2025 to reassert Congress’ constitutional role and ensure Congress has a voice in trade policy,” Grassley said in a statement last week. Six other Republican senators have co-sponsored the bill: Sens. Mitch McConnell (Ky.), Jerry Moran (Kan.), Todd Young (Ind.), Thom Tillis (N.C.), Lisa Murkowski (Alaska) and Susan Collins (Maine). The Democratic cosponsors are Sens. Amy Klobuchar (Minn.), Mark Warner (Va.), Michael Bennet (Colo.), Peter Welch (Vt.), Chris Coons (Del.) and Richard Blumenthal (Conn.). ...read more read less
