The C.E.O. of JPMorgan Chase, who has rarely taken on President Trump during his second term, wades into the argument over the Federal Reserve chair.

The Fed has been renovating two of its office buildings in Washington for several years at a current cost estimate of about $2.5 billion, $700 million more than originally expected. The project was first approved by the Fed's governing board in 2017.

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.
