President Donald Trump teased that tariffs could climb higher over time while responding to Maria Bartiromo's questions about business leaders' desire for predictability.

President Donald Trump downplayed a stock market selloff that began immediately after he announced 25% tariffs on Mexico and Canada. During an interview that aired Sunday on Fox News, host Maria Bartiromo asked Trump about his admission that there would be economic "disruption" because of his presidency.

In a big warning to Canada and Mexico, US President Donald Trump said tariffs on the United States' North American neighbours "could go up", but stressed that businesses will have clarity on the issue after April 2.
