The nomination hearing for Kevin Warsh, President Trump’s choice to replace Jerome Powell as chair of the Federal Reserve, has been postponed. Originally scheduled for April 16, the hearing will not proceed until the Senate Banking Committee receives Warsh’s necessary paperwork, according to sources familiar with the situation. A new date for the hearing has not yet been announced.

The delay stems from incomplete financial disclosure documents, which the committee must receive at least one week before the hearing to provide proper notice. The committee was required to collect Warsh’s filings by midnight on Thursday to maintain the initial timetable.

The complex nature of Warsh’s financial disclosures has contributed to the hold-up. Warsh’s portfolio is notably extensive, partly due to his marriage to Jane Lauder, heiress to the Estée Lauder fortune, who has an estimated net worth of $1.9 billion. When Warsh was last nominated in 2006 for a six-year term as a Federal Reserve governor, his disclosures detailed nearly 1,200 assets, most held by his wife.

Officials have described the delay as a “paperwork issue” similar to one experienced by Paul Atkins, former Securities and Exchange Commission chair, who also had intricate disclosures due to his high net worth. The Senate Banking Committee’s need to thoroughly review such complex filings underscores the procedural requirements tied to financial transparency in vetting candidates for high-level federal positions.

While the postponement has drawn attention to the thoroughness of disclosure requirements, it has not been characterized as an indication of controversy surrounding Warsh’s nomination. The committee is expected to reschedule the hearing once all necessary documents are complete and submitted.
