Donald Trump has threatened to increase tariffs on Canadian cars, trucks, auto parts and steel to 50% today, after trade negotiations between Washington and Ottowa broke down last week.

On Truth Social, the president blasted Canada, and said the new duties will go into effect on 1 January 2027.

Critics include Senator Chris van Hollen, ex-aide to Obama Tommy Vietor and ex-Republican congressman Adam Kinzinger

Democrats and other Donald Trump critics reacted incredulously to a New York Times report on Sunday that House Democratic leader Hakeem Jeffries met with Jared Kushner, the president’s influential son-in-law, to discuss possible areas of collaboration.

The reported meeting comes months ahead of the November midterm elections in which Democrats are favored to retake the US House, a development that would make Jeffries speaker. If they are in the majority, Democrats are expected to use their oversight power to aggressively investigate the Trump administration, including self-enrichment by the president and his family.
