Sen. Thom Tillis (R-NC), a Senate Banking Committee member, stated on April 26, 2026, that he is prepared to advance Kevin Warsh's confirmation as Federal Reserve chair to replace Jerome Powell, following assurances that a Justice Department investigation into Powell is closed. Tillis had previously vowed to block Fed nominations during the probe, linked to the Fed's headquarters renovation. Many details about the probe's origins and scope remain unverified.
