Do you think Trump's tariffs have made the economy worse?

U.S. Trade Representative Jamieson Greer is scheduled to speak with CNBC's Squawk Box on Thursday morning. The appearance comes as tariff policies face multiple court challenges and trade disputes with several U.S. economic partners continue.

Why it matters

Greer's remarks come a week after midterm elections in which most voters reportedly said Trump's tariff policies have made the economy worse. Tariffs are expected to become a major target for Democrats once they take majority control of the House and Senate.

The 50% tariffs on a range of Canadian goods are being challenged in multiple court cases, while Section 301 duties face similar legal scrutiny. The extraction does not specify the total value of affected trade or the timeline for any court rulings.

The players

Jamieson Greer

Jamieson Greer is the U.S. Trade Representative, responsible for leading American trade negotiations and policy.

The details

Greer's office is conducting an investigation into foreign excess capacity in the manufacturing sector, which could lead to additional tariffs. Separately, reports indicate Treasury Secretary Scott Bessent pressed Commerce Secretary Howard Lutnick in a White House Situation Room meeting over his resistance to export controls, a claim a Commerce Department spokeswoman denied.

Market Dynamics

The Section 301 duties under the Trade Act of 1974 are now being challenged in court, while Greer's investigation into foreign excess capacity could extend that same authority to new tariffs. Together these developments mark a legal and policy test of how far Washington can rely on that statute.

Ongoing tariff disputes and pending court rulings on Section 301 and Canadian duties could change the cost of imported goods and the outlook for companies exposed to trade policy. Investors and households tracking these developments should watch the outcome of the litigation and any new tariffs that follow the excess capacity investigation.

The takeaway

Tariff policy is now being tested in courts and in the political arena at the same time, so its direction could shift as legal rulings and new elected majorities take shape. Readers tracking household costs or investment exposure should follow both the litigation and the excess capacity investigation.

What happens next

Greer is scheduled to speak with CNBC's Squawk Box on Thursday morning, and the outcome of the pending court challenges to the Section 301 and Canadian tariffs remains to be determined.
