The U.S. Agency for International Development is at the center of a political firestorm after the Trump administration indicated it will shut it down as an independent agency and possibly move it under the U.S. State Department in a larger effort to crack down on federal bureaucracy.

President Donald Trump said Monday afternoon that he would delay tariffs on Canadian imports for 30 days in exchange for the neighboring nation’s commitment to tackle drug trafficking and security issues at the U.

There are no tariffs on trade between Canadian provinces. But barriers do exist including inconsistent regulations, rules around transportation and provincial protectionism.
