Less than a month into his second term, U.S. President Donald Trump has already threatened to impose tariffs on half a dozen allies and adversaries.

Mark Rendell is the Globe’s Economics Reporter. He’ll explain how Trump is using tariffs, its role in achieving his administration’s vision for U.S. trade, and whether all of this... could actually backfire.

At universities across Canada, requests for disability accommodations are on the rise. Since the 2013-2014 school year – the number of students requesting accommodations – has doubled to 12 per cent.
