"The Fed has been plagued by deeply disturbing ethics scandals in recent years involving at least six Fed officials, so it's critical that the next chair have no financial conflicts – none," Warren said. "You have more than $100 million in investments that you have refused to disclose to ethics officials and to the public, so let me ask, do the Juggernaut fund or the TSDFS LLC invest in any companies affiliated with President Trump or his family, companies that have facilitated money laundering, Chinese-controlled companies or financing vehicles established by Jeffrey Epstein?"

Warsh agreed that ethics scandals undermined the Fed's credibility, but Warren redirected him.

"Answer my question please," she said. "I ask, you have $100 million in undisclosed assets, and what I'm asking is, are any of those with this outfit that invests in us companies affiliated with President Trump or his family, companies that have facilitated money laundering, Chinese-controlled companies or financing vehicles set up by Jeffrey Epstein? It's a yes-or-no question."
