Testifying before the Senate Finance Committee Wednesday, Commerce Secretary Wilbur Ross explained to Senator Michael Bennet (D-CO) exactly why the Trump administration’s plan to hold China accountable for dumping steel globally requires applying sanctions to allies such as Canada.

A partial transcript follows:

SEN. MICHAEL BENNETT: “What is the national security rationale for putting a tariff on the Canadian steel industry, with whom we have a trade surplus?”
