Kevin Warsh, President Donald Trump’s nominee for chairman of the Federal Reserve Board of Governors, has said he intends to bring reform to the Fed if confirmed. While he will have some latitude to steer the central bank, he will also face a number of obstacles to any course he tries to chart.

The Senate Banking, Housing, and Urban Affairs Committee is set to vote on advancing Warsh’s nomination on Wednesday, and his confirmation will then head to the Senate for a full vote. He is meant to replace outgoing Fed Chairman Jerome Powell and has pledged to make significant changes at the central bank.
