Federal Reserve Governor Lisa Cook plans to file a lawsuit contesting her dismissal by President Donald Trump, potentially triggering a legal confrontation between the White House and the U.S. central bank.
"President Trump has no authority to remove Federal Reserve Governor Lisa Cook," her lawyer Abbe David Lowell said in a statement, News.Az reports citing BBC.
The president has said there was "sufficient reason" to believe Cook had made false statements on her mortgage, and cited constitutional powers which he said allowed him to remove her.
The unprecedented move comes as Trump has put increasing pressure on the Fed - especially its chair Jerome Powell - over what he sees as an unwillingness to lower interest rates.
Long-term US government bonds were sold off on Tuesday, suggesting that investors are concerned about the Federal Reserve's independence after Trump's attempt to fire one of the central bank's governors.
If investors start to doubt the Fed's credibility, borrowing costs for the US government could rise – and that would have knock-on effects around the world since they are used to set the price of assets.
Cook is one of seven members of the Fed's board of governors, and in this position sits on the 12-member committee which is responsible for setting interest rates in the US.
"His attempt to fire her, based solely on a referral letter, lacks any factual or legal basis," Cook's lawyer said on Tuesday. "We will be filing a lawsuit challenging this illegal action."
The Federal Reserve weighed in too.
"Congress, through the Federal Reserve Act, directs that governors serve in long, fixed terms and may be removed by the president only 'for cause'," the central bank said in a statement. "Long tenures and removal protections for governors serve as a vital safeguard, ensuring that monetary policy decisions are based on data, economic analysis, and the long-term interests of the American people."
On Cook's planned lawsuit against Trump, the bank said it would abide by any court decision.
On Tuesday, President Trump said he had several "good people" in mind to replace Cook.
"We need people that are 100% above board and it doesn't seem like she was," Trump told reporters at a cabinet meeting.
The US president nominates candidates for the role, so removing Ms Cook would mean she could be replaced by someone more favourable to lower interest rates and to the Trump economic agenda.
The Fed's decision affects the rate at which Americans can borrow money as well as the savings rates on their bank accounts. US interest rates are also closely watched by central banks who set monetary policy in other countries.
She was appointed by Trump's predecessor, Democrat Joe Biden, in 2022 and is the first African American woman to serve in the role.
Trump's decision to remove her will likely raise legal questions, with experts suggesting the White House will need to demonstrate - potentially in court - that it had sufficient reason to fire her.
Cook said in a statement that Trump "purported to fire me 'for cause' when no cause exists under the law, and he has no authority to do so".
"I will not resign. I will continue to carry out my duties to help the American economy as I have been doing since 2022," she added.
The president had called for Cook's resignation last week over the allegation of mortgage fraud, which was first made in a public letter from housing finance regulator, Bill Pulte, a Trump ally, to Attorney General Pam Bondi.
The housing finance regulator called the letter a "criminal referral" and urged the justice department to investigate. It is not clear whether an investigation has been opened.
Cook voted alongside Powell and most other members of the committee to maintain US interest rates at the Fed's last rate-setting meeting at the end of July.
