Move would allow president-elect to implement broad tariffs after threatening Panama, Greenland and Canada

Donald Trump is mulling over the idea to declare a national economic emergency to impose widespread tariffs, CNN reports, as the president-elect escalates threats to seize the Panama Canal, acquire Greenland and force Canada into becoming a US state.

The emergency powers move would allow Trump to implement broad tariff measures against both allies and adversaries through the International Economic Emergency Powers Act, according to four sources familiar with the discussions.
