Warsh faces scrutiny over wealth

The criticism comes ahead of Warsh's scheduled confirmation hearing next week, which Democrats are attempting to delay.

Lawmakers have raised concerns about potential conflicts of interest given Warsh's ties to private equity and the financial sector.

The nomination is already complicated by an ongoing probe into current Fed Chair Jerome Powell, whom Trump has threatened to fire.

Warsh must win the support of a divided Senate Banking Committee to secure the role, which would give him significant influence over the U.S. economy during a period of high inflation.
