Warsh's path to the committee vote had faced a significant obstacle. North Carolina Republican Sen. Thom Tillis had pledged to block Warsh's nomination unless the Department of Justice dropped a criminal investigation into Federal Reserve Chair Jerome Powell. The probe was purportedly focused on cost overruns tied to a multibillion-dollar renovation of the Fed's Washington headquarters. But Powell, in a statement disclosing the investigation in January, said the administration was targeting him because of the Fed's interest rate decisions.
Even after a federal judge blocked grand jury subpoenas from being issued, Trump continued to back the investigation, which was being run by U.S. Attorney Jeanine Pirro. As recently as last Wednesday, Pirro was publicly committed to pursuing an appeal, only to reverse course two days later and announce the probe was being closed. With that obstacle removed, Tillis withdrew his objection to Warsh's nomination.
The committee action Wednesday unfolded just ahead of the Fed's scheduled interest rate announcement, which could mark one of Powell's final acts as chair. Persistent inflation and a labor market that has remained largely resilient have kept the Fed from moving aggressively on rate cuts — a restraint that Trump has repeatedly criticized and that has fueled an ongoing clash between the president and Powell.
