Kevin Warsh has clashed with Democratic senators during a fiery confirmation hearing to decide whether he should be installed as Federal Reserve chairman. From suggestions that he would be President Donald Trump's 'sock puppet' to questions over his links to paedophile financier Jeffrey Epstein, here are the key takeaways from Tuesday's showdown in the Senate.

Senator Elizabeth Warren, the ranking Democrat on the banking committee that is overseeing his confirmation, stated that Warsh would be little more than Trump's 'sock puppet'. Trump has suggested that if confirmed, Warsh would conform to his agenda and lower interest rates, which the president argues is necessary to boost the US economy. Trump's public clashes with current Fed chairman Jerome Powell, especially on interest rates, add to the tension, as Powell's term expires in May.

During the hearing, Warren stated, 'Having a sock puppet in charge of the Fed would give the president access to the Fed's powerful authorities to enrich himself, his family, and his Wall Street buddies.' When asked if he would indeed be the president's sock puppet, Warsh responded: 'Absolutely not.' He affirmed that the independence of America's central bank is essential and voiced his commitment to preserving its self-governance.

Warren, who opposes Warsh's appointment, also questioned him over his potential links to Jeffrey Epstein, highlighting his disclosed financial holdings, including a significant investment fund. Warsh declined to answer directly if his investments were linked to Trump or Epstein, but stated that he planned to divest his holdings upon confirmation.

Warsh also utilized the hearing to deny any deals with Trump regarding interest rates, asserting, 'The president never once asked me to commit to any particular interest rate decision, period.' However, Senator Ruben Gallego pointed out that previous reports suggested Trump had pressed him to lower borrowing costs.

Despite partisan divides, one Republican, Senator Thom Tillis, withheld support for Warsh's confirmation, seeking an inquiry into outgoing Fed chairman Powell's handling of an overspending case.

Warsh promised a 'regime change' at the Fed, pledging to overhaul how it measures inflation and communicate policy changes without 'rehearsed scripts'. His vision indicates potential shifts in the Fed's approach to monetary policy, though the specifics remain unclear.
