Kevin Warsh's Federal Reserve chair nomination hearing, originally scheduled for April 16, has been postponed. The Senate Banking Committee requires one week's notice and must first receive Warsh's financial disclosures and paperwork. A criminal investigation into current Fed chair Jerome Powell and Senator Thom Tillis's blockade have also delayed the process. Warsh, married to Estée Lauder heir Jane Lauder, must resolve complex financial disclosures before proceeding.
