Powell, who was appointed by Trump in 2017, issued a rare video message on Sunday night rebuking the investigation as a politically motivated effort to influence the Fed's interest rate policy.

Former Federal Reserve chiefs, Republican senators and — perhaps most important, many bond investors — raised concerns about an investigation into the bank’s leader.

Jerome Powell said he believed the investigation was due to Donald Trump's anger over the Fed's refusal to cut interest rates.
