The Washington Post reports:
President Donald Trump said Tuesday that he had ordered a doubling of the tariff on Canadian steel and aluminum in response to Ontario Premier Doug Ford’s imposition of a new tax on electricity supplied to three U.S. states. Ford’s action was itself a response to Trump’s earlier tariff move.
Trump also said without providing details that he would soon declare a “National Emergency on Electricity within the threatened area,” an apparent reference to portions of Minnesota, Michigan and New York, which depend upon Ontario for some electricity supplies.
He issued a separate series of demands for Canada to drop existing tariffs on imports from the United States of agricultural products and repeated his insistence that Canada “become our cherished Fifty First State.”
