Powell's testimony to members of Congress has become the focus of a high-risk investigation by the Department of Justice.

Federal Reserve Chairman Powell was very clear to Congress that the Fed's renovation project does not include a bee farm, a rooftop garden, or luxury marble decorations. There are no new fountains or high-end marble. There are no private elevators or VIP restaurants. Powell's testimony has now become the core of a criminal investigation, with critics suggesting that he may have lied about project costs and luxury upgrades. Prior to the investigation, President Trump had been criticizing him for months, accusing Powell of failing on cost overruns and interest rate issues, but he has not yet brought any charges against Powell.
