Federal prosecutors made an unannounced visit Tuesday to the Federal Reserve's construction site as part of a Trump administration investigation into a $2.5 billion renovation project, but were turned away and referred to Fed attorneys. The investigation has found no evidence of a crime according to prosecutors' own concession in court last month, and a federal judge ruled the prosecutors' interest in the project was 'pretextual' — but the probe continues and has blocked confirmation of Trump's nominee to replace Fed Chair Jerome Powell. This standoff means Powell stays in office longer, which some Republicans view as undermining Trump's authority over monetary policy.
