Trump allies fear that the inquiry into the Fed chair could complicate the process of replacing him this year.

Fed chair Jerome Powell announced on Sunday President Trump's Justice Department is threatening criminal charges as "a consequence" for interest rates

The investigation, which is said to center on renovations of the Federal Reserve’s headquarters in Washington, is an escalation of the president’s long-running pressure campaign on Jerome H. Powell.

Powell took the unprecedented step of responding publicly to the news, and the inquiry sparked criticism from many Democrats and even some Republicans. Here are the most notable reactions. Powell has taken pains not to engage directly with President Trump’s many personal insults directed at him in recent months.

The Federal Reserve released a video statement Jan. 11 following the Justice Department’s launch of a criminal investigation into Chair Jerome H. Powell.

Three Republican senators offered a rare rebuke of the Trump administration’s tactics, criticizing an investigation of the Federal Reserve chair.

Jerome Powell isn't the first high-profile official to find himself targeted by the Justice Department since Donald Trump returned to the White House
