At some point during his Wednesday morning tweet spree, in between smearing a decorated war veteran and claiming Democrats are a “lost cause,” Donald Trump declared that he is responsible for the “Greatest Economy in American History!” This claim was not anything new—the president has made similar proclamations on a regular basis for the last three years—but the speed at which it was almost immediately shot down by his own government may have set a new record.

Less than an hour after dubbing his economy the best in the history of the universe, so good that all other economies should go home, the Commerce Department released data showing that, actually, the economy cooled off over the summer, growing at just 1.9%, annualized, from July through September, the latest indication that the global slowdown is hitting home. Economists had anticipated weaker growth thanks to Trump’s decision to kick his trade war with China up a notch in August. Unsurprisingly, that move scared business leaders and led them to pull back on major investments thanks to uncertainty surrounding when—or if—Trump would ever make a deal with Beijing. (His decision to lie about the prospect of a deal weirdly didn’t help.)

While consumer spending remains strong, business investment has now shrunk for six straight months, dropping 3% in the third quarter, representing the biggest fall since the end of 2015. Per the Washington Post, a bunch of companies have said they are halting investments because of economic uncertainty, “particularly related to whether trade rules will be shifting with China and other countries.”

After revving to 2.9% growth in 2018, the U.S. economy appears to be settling into a slower pace. Trump vowed during his presidential campaign that he could boost the economy to around 4% growth, a level not seen in years. He also has promised at least 3% growth a year, an annual pace he has yet to achieve.
