The advisers of President Donald Trump have discussed in recent days arranging a meeting between him and Federal Reserve Chairman Jerome Powell in the coming weeks, the Wall Street Journal reported on Sunday, citing a source.

Trump has recently been critical of the Fed for raising borrowing costs this year, especially as U.S. stocks have tumbled and yields on U.S. government debt have begun to signal a possible recession ahead.

Trump has frequently attacked Powell, who was sworn in as Fed chairman last February.

Powell hasn’t had a substantive conversation with Trump since he was announced as the president’s pick to lead the Fed in November 2017. Trump’s advisers in recent days have discussed arranging a meeting between the two men in the coming weeks, a person familiar with the matter told the Journal.

Reuters reported on Saturday that Trump has privately discussed the possibility of firing Powell. U.S. Treasury Secretary Steven Mnuchin later said Trump told him he had "never suggested firing" the Fed chairman.

The White House and the Federal Reserve did not respond to a request for comment outside regular business hours.
