President Donald Trump lashed out at Goldman Sachs Group Inc. on Tuesday, declaring in a Truth Social post that the bank’s forecasts about the economic fallout from his tariff agenda were “wrong” and that its chief executive officer, David Solomon, should “go out and get himself a new economist—or just focus on being a DJ.” Trump said Goldman “made a bad prediction a long time ago on both the market repercussions and the tariffs themselves” and “refuse to give credit where credit is due.” Solomon, who has occasionally performed as a disc jockey under the name “D-Sol,” has been one of Wall Street’s most outspoken critics of the administration’s trade policies. The clash comes a week after the latest round of Trump tariffs took effect, lifting import duties on a wide range of goods to between 10% and 50%. Goldman economists had warned the measures could weigh on growth and raise consumer costs—assessments the president again rejected in his post. Goldman Sachs, which has a market value of about $220 billion, has not publicly responded to the remarks.
