Congresswoman Elise Stefanik says she's against President Trump's trade war with Canada and other U.S. allies. The Republican lawmaker spoke in Plattsburgh Friday. "I am concerned about the punitive impact of tariffs because of this ongoing trade war," Stefanik said. "When it comes to targeting China, let's target China and not our important allies and trading partners like Canada, like our allies in Europe."Stefanik also thinks Congress should have more of a say in the fate of the North American Free Trade Agreement, or NAFTA. She said she supports modernizing and renegotiating NAFTA but not tearing it up, as President Trump has threatened. She said the White House shouldn't be able to unilaterally pull the U.S. out of a trade deal. Then, speaking with reporters, Stefanik took a few swings at Democrat Tedra Cobb from Canton. Stefanik is up for reelection this fall, and she faces a challenge from Cobb and Green Party candidate Lynn Kahn. And it's gearing up to be a bitter campaign.
