Senate Democrats have taken action to delay the confirmation hearing for Kevin Warsh, nominated by former President Donald Trump to replace Jerome Powell as chair of the US Federal Reserve. In a letter to Senator Tim Scott, the Democratic members of the Senate banking committee expressed concerns about Trump's attempt to exert control over the Fed while investigations into Powell and Fed Governor Lisa Cook are ongoing. Powell is under investigation related to the renovations of the Fed's headquarters, which he claims are politically motivated, while Cook faces scrutiny after Trump attempted to fire her over alleged mortgage fraud, a claim she denies. The Democratic senators stated that it would be 'absurd' for Trump to appoint a new chair during this tumultuous period. Some Republican senators, including Thom Tillis, have also indicated they will not support Warsh's nomination until the investigations are resolved. Trump has continued to criticize Powell and the judicial system, alleging corruption without providing evidence. This political maneuvering reflects the ongoing conflict between the Trump administration and the Federal Reserve, complicating the future of monetary policy leadership in the US.
