Senator Thom Tillis announced Sunday that he is prepared to advance the confirmation of Kevin Warsh as Federal Reserve chair nominee, signaling a potential breakthrough in the nomination process.

The Republican senator said he had received assurances from federal prosecutors that addressed his previous concerns about the nomination. These assurances appear to have resolved issues that had previously caused Tillis to withhold his support.

Tillis's decision sets the stage for a key committee vote on Warsh's nomination to lead the central bank. The senator's support is considered crucial for advancing the nomination through the confirmation process.

Warsh, who previously served on the Federal Reserve Board of Governors from 2006 to 2011, has been nominated to head the nation's central banking system. His confirmation would place him in charge of monetary policy decisions that affect interest rates, inflation, and employment across the United States.

The timeline for the committee vote has not been announced, but Tillis's statement removes a significant procedural hurdle that had been blocking progress on the nomination.
