U.S. President Donald Trump warned on Wednesday that an impeachment inquiry against him could derail congressional approval of a North America trade pact, dragging down Mexico’s peso and stock market as investors fled riskier assets. While U.S. Trade Representative Robert Lighthizer said he was confident the U.S-Mexico-Canada trade agreement (USMCA) would come up for a vote and pass, Trump told him in front of reporters that he knows “these people” better, referring to Democrats.
