President Donald Trump visited the Federal Reserve headquarters in Washington Thursday, where he publicly scorned Fed chairman Jerome Powell over the costs of a long-planned, roughly $2.5 billion renovation project.

The administration has repeatedly criticized Jerome H. Powell, the chair of the central bank, for his handling of the economy and the cost of work on the institution’s headquarters.

The president’s participation in a tour of the Fed had the makings of a public relations disaster for the central bank. But by Friday, the president was praising Powell.
