Sen. Elizabeth Warren (D-Mass.) on Tuesday blasted the resignation of Federal Reserve Governor Stephen Miran from his White House post, calling the move “141 days too late” and renewing her charge that he has been a political loyalist to President Donald Trump rather than an independent policymaker.

Warren Revives ‘Sock Puppet’ Charge Against Miran

“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, where she also reposted a clip from Miran’s September 2025 confirmation hearing.

In the video, she presses him on whether Trump lost the 2020 election. Miran repeatedly sidesteps, saying only that “Joe Biden was certified by Congress as the president of the United States.”

Miran Defends Timing In Letter To Congress

According to an Associated Press account of his resignation, Miran, a Harvard-trained economist and former hedge-fund strategist, was tapped by Trump last year to chair the White House Council of Economic Advisers and later to fill a vacant seat on the Fed’s Board of Governors. His Fed term formally expired Jan. 31, but under law he can stay until a successor is confirmed, even as he now steps down from the White House role.

In a resignation letter obtained by Politico and other outlets, Miran wrote, “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.”

Debate Over Fed Independence Intensifies Under Trump

Miran has been a prominent defender of Trump’s tariff-heavy trade agenda and an advocate of lower rates, positions that drew criticism from Democrats worried 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.

His exit from the Council comes as Trump moves to remake the central bank’s leadership more broadly, nominating former Fed Governor Kevin Warsh to succeed Chair Jerome Powell when his term ends in May, a choice that has already stirred market jitters and fresh warnings from Warren that Trump is trying to install “puppets” at the Fed.
