Elon Musk has told Justin Trudeau he “doesn’t matter” after the outgoing Canadian prime minister dismissed Donald Trump ’s plan for the U.S. to take over its northern neighbor. The key adviser to the president-elect jabbed Trudeau on his X social media platform (formerly Twitter) after Canada’s premier announced Monday he is to resign.

Canadian Prime Minister Justin Trudeau is expected to announce his resignation amid increasing pressure from his Liberal party, according to reports.

The development comes a month after Canada's deputy prime minister, Chrystia Freeland, resigned suddenly from Trudeau's cabinet.
