The U.S. stock market is sinking further Tuesday after President Donald Trump raised the stakes in his trade war, pulling Wall Street more than 9% below its record set just a month ago. The S&P 500 was down 0.

Trump threatened to double the tariff on Canadian metals after the leader of Ontario put a surcharge on energy sales to the U.S. Meanwhile, the House of Representatives narrowly passed a short term government funding bill and Ukraine approved a potential 30 day ceasefire plan.

A major sell-off of stocks on Wall Street continued Tuesday on the heels of an intensifying trade war between the U.S. and Canada.

The selloff on Tuesday extended a days-long market decline touched off by U.S. tariffs imposed last week on Canada, Mexico and China, some of which were delayed.
