As stock markets tumble in the aftermath of President Donald Trump's sweeping tariffs, Republicans in Congress were watching with unease and talking of clawing back their power to levy tariffs — but almost none seemed ready to turn their words into action.

Stock market indices have sharply fallen on the heels of President Trump imposing higher tariffs on more than 180 countries.

Sen. Chuck Grassley (R., Iowa) joined with Sen. Maria Cantwell (D., Wash.) to introduce a bipartisan bill on Thursday that would rein in the president’s power to impose tariffs, allowing Congress to remove tariffs put in place by the administration.
