Kevin Warsh, the nominee to lead the US Federal Reserve, has faced criticism and backlash from Democrats questioning his financial disclosures and potential conflicts of interest. The independence of the Fed remains a key issue for many lawmakers concerned about US President Donald Trump's influence over any Senate-confirmed candidate. Massachusetts Senator Elizabeth Warren warned that confirming Warsh could result in the Fed granting special accounts to the Trump family's crypto company or providing bailouts to his friends on Wall Street if they get into trouble. Warsh also faced questions on his position on lowering interest rates, an action Trump has called for and signaled his pick would push if confirmed. The likelihood of a delay in Warsh's confirmation is fueling an active event contract on prediction markets platform Polymarket.
