WASHINGTON (Reuters) -Federal Reserve Chair Jerome Powell has asked the U.S. central bank's inspector general to review the costs involved in the renovation of its historic headquarters in Washington, as Trump administration officials intensify their criticism of how the Fed is being run.

President Donald Trump ramped up the pressure on Jerome Powell, attacking the Federal Reserve Chair over the costly renovation of the central bank’s headquarters and again calling for him to step down.

In an interview with ABC News, Kevin Hassett was also pressed about the president's decision to hit imports from Brazil with steep tariffs.
