Federal Reserve Chair Jerome Powell is under fire from the White House, which accuses him of bungling a yearslong renovation of the Fed's headquarters and has suggested that it could be cause to fire him.

President Donald Trump signed the HALT Fentanyl Act, which aims to combat the fentanyl crisis into law, during an event in the East Room of the White House. Trump was accompanied by various lawmakers and family members who have lost loved ones to the epidemic.

In a letter Thursday, the Federal Reserve chief rejected criticism the White House has leveled at him over the cost of renovation projects.
