The US Justice Department is halting its investigation into the Federal Reserve chairman, Jerome Powell, over claims regarding excessive costs tied to building renovations. US Attorney Jeanine Pirro announced that the inquiry will transition to an internal review under the Fed’s inspector general. This decision emerges amidst a long-standing tension between President Donald Trump and Powell, particularly focused on the Fed's renovation expenses. Trump has publicly criticized the financial outlays for these renovations, which reportedly far exceed initial estimates, stating they could total up to $3.1 billion compared to the Fed's own forecast of $2.5 billion. This investigation's conclusion arrives as Powell nears the end of his term, with the Senate currently considering Trump's nominee, Kevin Warsh, for the position. Amidst this political dynamic, the White House maintains confidence that Warsh's confirmation will proceed swiftly, as they seek to establish a leadership that embodies competence in Fed decision-making. Powell has previously challenged the nature of the investigation, arguing it stemmed from Trump’s discontent over the Fed's refusal to follow political pressure regarding interest rate cuts. As the renovations aim to modernize historical buildings and tackle issues like asbestos, Powell's leadership and independence are now under scrutiny as he prepares to transition leadership within the Fed.
