The Democratic majority in Congress will now control trade committees and be able to investigate tariff policy, but repealing tariffs runs into Trump’s veto power. With at least 235 seats, according to Reuters projections, Democrats will hold trade committee chairs and have an easier time passing trade legislation.

Democrats want to rescind old laws Trump used to impose tariffs, such as Section 338 of the 1930 Tariff Act, applied to Canadian imports. For Blake Harden of Ernst & Young, the congressional swing is “very unlikely” to have a significant impact on the president’s trade agenda and the tariffs in place — Trump will continue to pursue his tariff-driven trade agenda protecting workers, farmers and businesses, White House spokesman Matthew Middleton said.
