WASHINGTON (Reuters) - President Donald Trump met on Wednesday with Stanford University economist John Taylor in his search for a new chair of the Federal Reserve, a White House official said. Trump was joined for the meeting by Vice President Mike Pence and members of his team helping in his search for a Fed chair, including Treasury Secretary Steve Mnuchin, the official told Reuters. Trump is working from a short list that includes Jerome Powell, a Fed governor, Kevin Warsh, a former Fed governor, his top economic adviser Gary Cohn, and current Fed Chair Janet Yellen, whose term expires in February, sources have said.
