President Donald Trump, gearing up for the official start of his 2020 campaign, warned that the U.S. would face an epic stock market crash if he’s not re-elected. “If anyone but me takes over,” Trump told his 61 million Twitter followers on Saturday, “there will be a Market Crash the likes of which has not been seen before!” Trump officially starts his 2020 campaign on Tuesday with a rally in Orlando, Florida, and appears to be road-testing some of the themes he’ll be touching on in the next 18 months, including stoking fear of a market meltdown.
