A bogus rumor that President Donald Trump was considering a pause in tariffs briefly lifted markets Monday before the White House shot down the unfounded reports. The confusion — which was amplified on social media and by some traditional media outlets — lasted less than a half hour but reflected a jittery mood on Wall Street as stocks plunged over worries that Trump’s tariffs could torpedo the global economy. The origin of the false report was unclear but it appeared to be a misinterpretation of comments made by Kevin Hassett, director of the White House National Economic Council, during a Fox News interview earlier Monday morning.
