House Ways and Means Chairman Kevin Brady said he and Washington Rep. Dave Reichert, who chairs the Trade Subcommittee, are circulating a letter for signatures that will encourage Trump to “tailor his actions” on the tariffs.

“My view is the president should exempt all fairly traded steel and aluminum from every country that trades fairly,” Brady said. “Certainly Canada and Mexico. Canada is a huge customer for the U.S. Mexico is a key trading partner.”

When asked if Congress could pursue legislation to block or limit the tariffs if Trump does not tailor them on his own, the Texas Republican wouldn’t go there.
