Trump has also threatened to introduce tariffs - a tax on imports - on goods from Canada and Mexico, but paused these for 30 days after both countries agreed to boost border security. The US president has said tariffs are needed to help the American economy and to "protect" the country from the "major threat of illegal aliens and deadly drugs".

President Donald Trump acknowledged that consumers could soon feel the financial burn of his economic plan, which includes sweeping tariffs on Canada, Mexico and China. The revelation came Monday as Trump’s 40-minute-long Super Bowl night sit-down with Fox News host Brett Baier aired.
