WASHINGTON 鈥 US Federal Reserve Governor Lisa Cook will file a lawsuit to prevent President Donald J. Trump from firing her, a lawyer for the embattled central bank official said on Tuesday, kicking off what could be a protracted legal fight over the White House鈥檚 effort to shape US monetary policy.

鈥淗is attempt to fire her, based solely on a referral letter, lacks any factual or legal basis. We will be filing a lawsuit challenging this illegal action,鈥 Ms. Cook鈥檚 lawyer, prominent Washington attorney Abbe Lowell, said in a statement.

The statement was issued a day after Mr. Trump said he would fire Ms. Cook, the first Black woman to serve on the central bank鈥檚 governing body, for alleged 鈥渄eceitful and potential criminal conduct鈥 related to mortgages she took out in 2021.

Mr. Trump鈥檚 attempt to remove her, unprecedented in the 111-year history of the nominally independent US Federal Reserve Board, is consistent with his style of breaking norms and prompting opponents to challenge him in court.

It follows other largely successful efforts to bring other elements of the US government under his direct control. Since returning to office in January, the President has overseen the departure of hundreds of thousands of civil servants, dismantled several agencies and withheld billions of dollars of spending authorized by Congress.

鈥淲e need people that are 100% above board and it doesn鈥檛 seem like she was,鈥 Mr. Trump told reporters at a meeting. He said he had several 鈥済ood people鈥 in mind to replace Ms. Cook but would abide by any court decision that left her in her job.

Mr. Trump pressured the Fed to lower interest rates during his first term in the White House and he has escalated that campaign in recent months. The President has demanded that rates be cut by several percentage points and threatened to fire Fed Chair Jerome Powell, although he recently backed down from that.

Ms. Cook鈥檚 departure would allow Mr. Trump to pick a majority of the Fed鈥檚 seven-member board, including two incumbents and the pending nomination of White House economist Stephen Miran. Mr. Trump said he may consider Mr. Miran, whom he nominated for a temporary seat on the Fed board that is due to expire in January, for Ms. Cook鈥檚 seat should it become vacant. The Wall Street Journal reported that former World Bank Group President David Malpass, a long-time Mr. Trump ally, was also discussed for the job.

The Fed said in a statement that Ms. Cook and other board members serve 14-year tenures and cannot be removed easily from office, in order to ensure that monetary policy decisions are based on economic data and 鈥渢he long-term interests of the American people.鈥

Though Mr. Trump on Monday said Ms. Cook鈥檚 firing was 鈥渆ffective immediately,鈥 the Fed鈥檚 statement indicates that it sees Ms. Cook鈥檚 status as unchanged. The central bank next meets to set interest rates on Sept. 16鈥17, and based on the Fed鈥檚 statement it appears it would take a court ruling between now and then for her to be prevented from participating.

The attempt to influence US monetary policy has shaken confidence in the dollar and US sovereign debt and sparked fears of global financial turmoil.

Wall Street鈥檚 main equities indexes closed slightly higher on Tuesday, while the dollar dropped. The yield curve on US Treasuries steepened on Tuesday as Mr. Trump鈥檚 attempt to fire Ms. Cook raised concerns about the US central bank鈥檚 independence and the prospect of a potentially more dovish composition of Fed policymakers.

Mr. Trump said in a letter to Ms. Cook on Monday that he had 鈥渟ufficient cause鈥 to fire her because she had described separate properties in Michigan and Georgia as primary residences on mortgage applications before she joined the Fed in 2022.

In recent months Mr. Trump has fired several Black women who held senior government positions, including the head of the Library of Congress and the chair of the National Labor Relations Board.

MORTGAGE QUESTIONS
William Pulte, a Trump appointee who is director of the Federal Housing Finance Agency, first raised questions about Ms. Cook鈥檚 mortgages last week and referred the matter to US Attorney General Pamela Bondi for investigation. Ms. Bondi has yet to say whether the Justice department will take action.

Ms. Cook took out the two mortgages in question when she was an academic.

She is due to serve on the Fed board through 2038, but the Federal Reserve Act of 1913 allows removal of a sitting governor 鈥渇or cause.鈥

Until now, that power has not been tested. US presidents have largely taken a hands-off approach to Fed matters to ensure confidence in monetary policy.

Peter Conti-Brown, a scholar of the Fed鈥檚 history at the University of Pennsylvania鈥檚 Wharton School, noted that the mortgage transactions preceded her appointment to the Fed and were in the public record when she was vetted and confirmed by the Senate.

鈥淭he idea that you can then reach back, turn the clock backward and say, you know, 鈥楢ll these things that have happened before now constitute fireable offenses from your official position鈥 is to me incongruous with the entire concept of 鈥榝or cause鈥 removal,鈥 Mr. Conti-Brown said.

Academic research has found that policymakers who are allowed to manage inflation independent of political meddling generally achieve better outcomes.

鈥淭he Fed as an institution escaped harm in the first Trump administration, and will not be so fortunate this time around,鈥 said Tim Duy, chief US economist at SGH Macro Advisors. 鈥 Reuters
