重大翻盘！美众议院否决对加拿大加征关税，6名共和党人倒戈

Core Viewpoint - The U.S. Congress has achieved a significant victory against President Trump's tariff policy, opening the door for multiple votes aimed at challenging this key economic policy [1][2]. Group 1: Congressional Actions - The House of Representatives voted 217 to 214 to reject a procedural motion to postpone tariff-related resolutions until August [1]. - A subsequent vote aimed at blocking Trump's tariffs on Canada passed with a larger margin of 219 to 211 [1]. - Six Republican representatives joined nearly all Democrats to pass the joint resolution aimed at terminating Trump's national emergency declaration regarding tariffs on Canada [1][2]. Group 2: Context and Implications - This vote is seen as largely symbolic, as Trump could veto the resolution if it reaches his desk, but it marks the first congressional review of Trump's national emergency declarations in 13 months [2]. - The resolution specifically targets one of Trump's most controversial executive orders, with little evidence supporting the claim that drug inflow from Canada constitutes a public health crisis [2][3]. - A recent report indicated that the majority of illegal fentanyl entering the U.S. is produced in Mexico, not Canada, contradicting the rationale for the tariffs [3]. Group 3: Political Dynamics - The ongoing congressional battle over tariffs coincides with anticipation of a Supreme Court ruling on whether Trump has the legal authority to impose tariffs unilaterally after declaring a national emergency [4]. - Reports suggest Trump is considering withdrawing from the USMCA, a North American trade agreement, which is set for renegotiation this summer [4]. - Following the House vote, the Senate may also take up the issue, where opposition to Trump's tariffs has bipartisan support [4][5]. Group 4: Economic Impact and Future Outlook - The recent votes indicate a rare criticism from Trump's party, which has largely tolerated his unilateral tariff actions until now [5]. - Some Republican representatives have expressed that tariffs negatively impact the economy, burdening consumers, manufacturers, and farmers [5]. - The ongoing discussions around tariffs are expected to become a significant issue in the upcoming midterm elections, with Democrats likely to leverage low public support for tariffs against vulnerable Republican representatives [5].
