President Donald Trump is facing pressure from U.S. hospitals and generic drugmakers to exempt medical goods from his new tariffs on Chinese imports, as they join big pharma lobbyists who have said such trade barriers will cause shortages of medicines and higher prices in the United States.

The tariffs and US President Donald Trump's '51st State' comments have made way for a surge of patriotism in Canada.

Mexico and Canada get reprieves but tariffs on China go ahead, prompting retaliation.

Stocks swooned at the open on steep tariffs set to start Tuesday but mostly reversed losses on late morning news that the hit on goods from Mexico will be delayed for one month. It's been a wild ride.
