The Senate Finance Committee is set to hear testimony Wednesday from U.S. Trade Representative Jamieson Greer, who will defend President Trump's aggressive trade policies amid growing bipartisan concern over the economic fallout from new tariffs.
Greer is expected to face pointed questions from lawmakers about the administration's recent tariff announcements, including a fresh 50 percent levy on certain Canadian goods. The move, announced earlier this week, targets what the White House has labeled unfair trade practices by Ottawa. Canadian Prime Minister Mark Carney has condemned the tariffs as a violation of the U.S.-Mexico-Canada Agreement, drawing support from some Republican senators worried about rising costs for consumers.
In addition to the Canadian measures, the administration imposed a 25 percent tariff on Brazilian imports that took effect Wednesday. The broadsides against two major trading partners signal a renewed escalation in Trump's protectionist strategy, which has drawn both praise from hardline trade hawks and criticism from business groups and fiscal conservatives.
Greer's appearance comes as the White House pursues an increasingly confrontational trade posture. Earlier this month, Trump threatened a 100 percent tariff on generic drugs unless pharmaceutical companies shift production to the United States by 2028, a proposal that has rattled the healthcare industry. The administration has also weighed new sanctions and tariffs linked to geopolitical tensions, including threats to bomb Iranian infrastructure over attacks in the Strait of Hormuz.
Republican senators, already wary of the economic impact, have voiced unease over the latest tariffs on Canada. GOP lawmakers are particularly concerned about affordability for American families, as the levies risk raising prices on goods ranging from lumber to agricultural products. The hearing is likely to highlight the tension between Trump's base, which supports aggressive trade enforcement, and centrist lawmakers who fear a drag on the economy.
Democrats on the committee are expected to press Greer on the administration's broader trade strategy, including its impact on manufacturing jobs and supply chains. Some have called for a return to multilateral negotiations, arguing that unilateral tariffs alienate allies and fail to address systemic issues like Chinese overcapacity.
The hearing, scheduled to begin at 10 a.m. EDT, is being closely watched by markets and foreign capitals. Greer's testimony will provide the clearest signal yet of whether the administration intends to double down on its tariff campaign or seek a diplomatic off-ramp.
