A growing number of Republican lawmakers are calling to block a central bank digital currency from being issued in the U.S., and Rep. Alex Mooney of West Virginia is the latest to join the chorus.

However, Mooney’s bill, which was introduced in the House on Thursday, is different — he is calling for something called the Digital Dollar Pilot Prevention Act, which aims to prevent the Federal Reserve from launching a pilot program that would test the operability of a central bank digital currency (CBDC) in the U.S. financial system.

The move would stop the development of a CBDC in its tracks, people inside Mooney’s office tell FOX Business. While anti-CBDC legislation is nothing new, Mooney’s bill attempts to close the pilot program “loophole” that could allow the Federal Reserve to implement a test run of a CBDC without the consent of Congress.
