Kevin Warsh, President Trump’s nominee to serve as the next chair of the Federal Reserve, may face a tough fight for confirmation — partly over events for which he has no control.

The Senate Banking Committee holds a confirmation hearing for Warsh on Tuesday — but already one GOP senator has said he will block a vote on the nominee until the Department of Justice drops an investigation into the Fed.

Warsh will also likely face questions about inflation and borrowing costs and whether he can maintain his independence as Trump makes it clear he expects his next Fed chair to lead the charge to lower interest rates.
