After months of criticizing Federal Reserve Chair Jerome Powell, President Donald Trump took the fight to the Fed’s front door on Thursday, publicly scorning the central bank chief over the ballooning costs of a long-planned building project.

Trump is the first president to visit the Fed since President George W. Bush attended the swearing-in ceremony of Fed Chair Ben Bernanke in 2006. That ceremony marked only the third visit of a president to the Fed, Bernanke noted in his remarks on the day.
