President Donald Trump says he will double his planned tariffs on steel and aluminum from 25% to 50% for Canada, escalating a trade war with the United States' northern neighbor and standing unmoved by recent stock market turmoil and rising recession risks. Trump said on social media that the increase of the tariffs set to take effect on Wednesday is a response to the price increases that the provincial government of Ontario put on electricity sold to the United States. After a brutal stock market selloff on Monday and further jitters Tuesday, Trump faces increased pressure to show he has a legitimate plan to grow the economy instead of perhaps pushing it into a recession.
