Janet Yellen, who was chair of the Federal Reserve until 2018, said President Donald Trump lacks economic knowledge.

Yellen's policies as the Federal Reserve chairwoman helped lower unemployment and spur the country's economic recovery after the 2008 financial crisis, but her legacy will partially depend in part on her successor, Jerome Powell.

Powell is popular within the Federal Reserve system, where he's been a governor since 2012.

The administration is hoping to make a decision within the next two or three weeks, and President Donald Trump has already met with a few candidates.

The Fed's upbeat assessment of the economy contrasts with Trump's belief that the nation has only begun to embark on a path of economic renewal.

Trump's default mode is to describe all unwelcome facts as the result of cheating by his opponents.

The U.S. central bank said an array of global risks and other factors had convinced it to delay the hike.

After months of speculation, federal policymakers could raise interest rates on Thursday.

The Fed offered a strong signal that it was on track to raise interest rates sometime next year.
