Canada Responds to US Auto Tariffs; Trump Officials' Signal Messages on Yemen Ordered Preserved

Canadian Prime Minister Mark Carney announced potential retaliatory trade measures against the U.S. in response to President Donald Trump's proposed auto tariffs. These tariffs could significantly increase vehicle costs and negatively impact the global economy. Canada aims to minimize domestic impacts while maximizing effects on the U.S. economy. European nations are also signaling plans for retaliatory tariffs. Carney said he would speak with Trump after Trump announced 25% tariffs on auto imports. Carney emphasized Canada's sovereignty and the need to diversify trade relationships away from the U.S. He also announced a CA$2 billion fund to protect Canadian auto jobs. In a separate development, US District Judge James Boasberg ordered the Trump administration to preserve Signal app messages from March 11-15 discussing attack plans towards the Houthis in Yemen. The messages involved top officials, including Defense Secretary Pete Hegseth and National Security Adviser Mike Waltz.
