If you're going to serve on the Federal Reserve while also advising the president, timing is everything. Senator Elizabeth Warren (D-Mass.) made that abundantly clear on Tuesday when she blasted Federal Reserve Governor Stephen Miran's resignation from his White House position, saying the move came about four and a half months too late.

Warren Doubles Down on Independence Concerns

"Donald Trump's Fed Governor Stephen Miran is finally resigning from his White House job. 141 days too late. Once a Donald Trump sock puppet, always a Donald Trump sock puppet," Warren wrote on X, resurfacing a clip from Miran's September 2025 confirmation hearing where things got uncomfortable.

In the video, Warren presses him on whether Trump lost the 2020 election. Miran dodges the question repeatedly, offering only that "Joe Biden was certified by Congress as the president of the United States." Not exactly the kind of straight answer that builds confidence in Fed independence.

The Dual-Role Dilemma

Here's the setup: Miran, a Harvard-trained economist and former hedge-fund strategist, got tapped by Trump last year for two jobs. First, he was named to chair the White House Council of Economic Advisers. Then Trump nominated him to fill a vacant seat on the Fed's Board of Governors. His Fed term technically expired on January 31, but federal law lets him stay until a successor is confirmed, which creates an awkward limbo.

In a resignation letter obtained by Politico and other outlets, Miran attempted to clarify the timeline: "While I took an unpaid leave of absence from the Council to come to the Federal Reserve, I promised the Senate that if I should stay on the Board past January, I would formally depart the Council. I believe it is important to stay true to my word while I continue to perform the job at the Federal Reserve to which you and the Senate appointed me."

Trump's Fed Makeover Continues

Miran has been vocal about supporting Trump's tariff-heavy trade agenda and pushing for lower interest rates, positions that made Democrats nervous about Fed independence. White House spokesperson Kush Desai praised him as providing "brilliant insights and powerful advocacy on behalf of the president," calling Miran "an enormous asset" to Trump's economic team.

But Miran's departure is just one piece of a broader picture. Trump is actively reshaping the central bank's leadership, having nominated former Fed Governor Kevin Warsh to replace Chair Jerome Powell when his term ends in May. That nomination has already rattled markets and prompted fresh warnings from Warren that Trump is trying to install "puppets" at the Fed. The independence of America's central bank, long considered sacrosanct, is now very much in the political spotlight.
