The imbalance in President Trump’s treatment of America’s closest trading partners may come from his desire to make Canada the 51st state, some Canadians believe.

The special appellate court is weighing Trump's challenge to a decision by a federal trade court to throw out his tariffs because they exceeded his authority, but its "decision could be weeks away," The Washington Post said. The case is ultimately "expected to end up at the Supreme Court."

Trump has justified tariffs on goods from Canada, the top U.S. export market, by accusing it of failing to stop the cross-border flow of fentanyl, even though U.S. government data shows Canada accounts for only 1% of the fentanyl that enters the United States.
