(CNN) President Donald Trump overruled three of his top advisers in deciding to move ahead with his tariff threat against Mexico over immigration. And as he faced a stock market slide and opprobrium from key Republican senators on Friday, the President held firm, tweeting: "It's time!"
Trump's drastic tariff threat sent shockwaves through Washington, sparking concerns inside the White House and on Capitol Hill that a new trade offensive would scuttle efforts to ratify a replacement for the North American Free Trade Agreement -- and drag down the US economy, which relies heavily on Mexican-produced cars, machines and foodstuffs, just as the 2020 campaign is taking off.
