President Trump announced on social media late Thursday night that he was ending all trade negotiations with Canada because of a video ad paid for by the province of Ontario that quoted his Republican presidential predecessor Ronald Reagan criticizing tariffs.

The Trump administration is telling Colorado to stop importing gray wolves from Canada as part of the state’s efforts to restore the predators, a shift that could hinder plans for more reintroductions this winter.

Trump accuses Canada of ad fraud and Supreme Court interference over Reagan’s tariff stance and trade practices.

Air Canada also failed you. The Montreal Convention requires airlines to honor valid tickets and boarding passes. If there was a ticketing error, it should have worked with Lufthansa to resolve it immediately, not abandon you at the gate. Both airlines’ “not our problem” responses are unacceptable.
