U.S. Trade Representative Jamieson Greer was scheduled to appear Thursday morning on CNBC's Squawk Box, the network reported, a week after midterm elections that CNBC said put Democrats in position to take majority control of the House and Senate¹.

CNBC said import duties have led to trade disputes with several U.S. economic partners and that those policies would likely be a leading target for the incoming Democratic majorities¹. The network also said most voters in that election described the tariff policies as having made the economy worse, a finding it attributed to its own post-election reporting¹.

Some of the largest duties, including Section 301 tariffs and 50% tariffs on a range of Canadian goods, are already being challenged in court, CNBC reported¹. Trump and his administration have defended the tariffs after Republican midterm losses, according to the same account¹.

Greer's office is conducting an investigation into foreign excess capacity in manufacturing that could lead to additional tariffs, CNBC said¹.

Separately, CNBC cited Axios as reporting that Greer was in the White House Situation Room last Thursday when Treasury Secretary Scott Bessent asked Commerce Secretary Howard Lutnick why he had resisted export controls, including on Megaspeed, a company CNBC described as central to a scandal involving Nvidia CEO Jensen Huang¹. Axios, as summarized by CNBC, said Greer and other Cabinet officials supported the controls and that Trump said to proceed, while Lutnick continued to delay¹.

Commerce Department spokeswoman Kristen Eichamer told CNBC that Bessent and Lutnick had "no such conversation" in the Situation Room¹. CNBC marked the item as developing news¹.
