Donald Trump’s top economic adviser, Kevin Hassett, said he expected there was “nothing to see here” as the US Department of Justice pursues its criminal investigation of Jerome Powell, the Federal Reserve chair.

The Trump administration has faced a chorus of criticism in recent days after it emerged that the justice department had served the Fed with grand jury subpoenas, in a significant escalation of its extraordinary attack on the US central bank’s independence.

Allies of Trump spent months last year accusing the Fed of mishandling the multibillion-dollar renovations of its historic headquarters in Washington. Trump had repeatedly threatened legal action.
