President Trump expressed hesitation Friday about appointing his top economic advisor, Kevin A. Hassett, as the next Federal Reserve chair, despite praising his work. Trump's comments introduce further uncertainty into the search for a replacement for Jerome H. Powell, the current Fed chair.

Speaking at a health care event at the White House, Trump lauded Hassett, director of the White House National Economic Council, for his efforts in promoting the administration's economic policies, particularly on television. However, he also indicated a reluctance to move Hassett from his current role. "I actually want to keep you where you are, if you want to know the truth," Trump said, adding that Fed officials "don't talk much." He stated, "I would lose you. It's a serious concern to me."

Hassett had been considered a leading candidate to succeed Powell. The search process experienced disruption this week when the Justice Department issued grand jury subpoenas to the Fed concerning Powell's management of a $2.5 billion renovation of the central bank's headquarters in Washington.

The New York Times reported the criminal investigation on Sunday, prompting Powell to release a video that directly criticized the Trump administration for using the threat of [unspecified action].

The president's remarks suggest the Fed chair selection process remains fluid and subject to Trump's shifting priorities. The uncertainty surrounding the Fed leadership comes at a time when the central bank's monetary policy decisions are under intense scrutiny, particularly in light of concerns about inflation and economic growth. The ongoing investigation into the Fed headquarters renovation adds another layer of complexity to the situation. The next steps in the Fed chair selection process remain unclear.
