Donald Trump has issued a warning to Jerome Powell, the current chair of the US Federal Reserve, stating he would fire him if Powell remains in the position after his term ends on May 15. This ultimatum comes as Trump pushes for his nominee, Kevin Warsh, to take over the role. Warsh, a former Fed governor, has been critical of Powell's approach to interest rates, which Trump believes should be lowered. The Senate banking committee is set to hold Warsh's nomination hearing on April 21, but there are doubts about whether Republican senators can secure enough votes for his confirmation, particularly due to a criminal investigation into Powell regarding the Fed's renovation costs in Washington, DC. Senator Thom Tillis from North Carolina has expressed his intention to block Warsh’s nomination until the investigation concludes, labeling it as “absurd.” Trump has characterized the renovation project as potentially corrupt or incompetent, emphasizing the need for transparency. Powell has previously rebuked Trump’s claims, asserting that the Fed's decisions should be based on economic conditions rather than political pressure. The Supreme Court's stance on Trump's authority to dismiss Fed officials without cause remains uncertain, as it has yet to rule on a related case involving the firing of Fed governor Lisa Cook last summer.
