Former President Donald J. Trump has publicly criticized economist Paul Krugman, who previously wrote for The New York Times and now runs his own newsletter. Trump accused Krugman of consistently predicting economic downturns since Trump's 2016 election victory, claims that Trump says have been proven wrong by record-high market performance. Trump referred to Krugman as a "Deranged BUM" in response to Krugman's critiques of Trump's tariff policies, trade war strategies, and controversies surrounding jobs reports. The dispute highlights ongoing tensions between Trump and Krugman, with Trump emphasizing the strong market results during his tenure despite Krugman's negative forecasts.
