Federal Reserve governor Lisa Cook has sued President Donald Trump over his attempt to fire her, setting up a potential legal battle with implications for the US central bank's autonomy.

Cook has asked the court to declare Trump's firing order unlawful and void, also naming Fed Chairman Jerome Powell as a defendant.

Trump has stated there was sufficient reason to believe Cook made false statements regarding her mortgage and cited constitutional powers to remove her. In contrast, Cook maintains that no cause exists under the law for her dismissal.

The lawsuit follows increased pressure from Trump on the Fed regarding interest rate management, as Cook plays a critical role in the board responsible for setting these rates.

According to Cook's attorney, Abbe Lowell, the lawsuit challenges what he described as President Trump's unprecedented and illegal attempt to remove Governor Cook from her position, which he argues would be an unprecedented act in the history of the Federal Reserve Board.

Moreover, Cook's lawsuit raises a crucial question about the balance of powers and the accountability of the Federal Reserve, which traditionally operates independently of political influence.

While the president asserts he acted within his rights as outlined by the Federal Reserve Act, experts express skepticism about the validity of his claims.

The case is expected to face various legal challenges, potentially leading to a significant ruling from the US Supreme Court that could impact future relationships between the presidency and the Federal Reserve.

As the situation develops, it raises broader questions about the implications of presidential power over independent institutions in the United States, marking a pivotal moment for the financial governance in the nation.
