Sen. Chuck Grassley (R-Iowa), who co-sponsored bipartisan legislation to limit President Trump’s trade authority, said Tuesday that he thinks Congress has “delegated too much authority to the president.

Iowa Senator Chuck Grassley says he’ll continue drumming up support for his bill that would limit a president’s power to impose tariffs, even after President Trump vowed he’ll veto the measure if it reaches his desk.

U.S. Senator Chuck Grassley (R-Iowa) and U.S. Senator Maria Cantwell (D-Washington) are introducing a bill aiming to rein in President Trump's ability to impose tariffs.The measure would give Congress the final say on any tariffs and also requires the president to justify new tariffs with an analysis of their potential impact.

Sens. Chuck Grassley and Maria Cantwell authored the Trade Review Act of 2025, which would force Trump to notify Congress before enacting a new tariff.

In what she dubs the "dumbest trade war in American history," Senator Warren discusses the impacts of Trump's tariffs on the U.S. economy and Republicans breaking with Trump over tariff policy.
