Bissent said that Powell attending the Supreme Court Cook hearing would be a "mistake."

US Treasury Secretary Steven Mnuchin criticized Federal Reserve Chairman Jerome Powell's plan to attend a hearing at the US Supreme Court on Wednesday regarding President Donald Trump's attempt to dismiss Federal Reserve Board member Lael Brainard. Mnuchin, speaking at the World Economic Forum in Davos, Switzerland on Tuesday in an interview with CNBC, said, "I actually think that's a mistake. Because if you want to avoid the politicization of the Fed, having the Fed Chairman sit there and try to put his finger on the scale is a serious mistake." Mnuchin made these comments as the US Supreme Court plans to hold a hearing on Wednesday to consider Trump's attempt to dismiss Brainard. According to an anonymous source, Powell plans to attend the hearing.
