The Senate Barrier. Former U.S. government official Ann Kelly explained on social media the challenges surrounding the Senate's schedule for the cryptocurrency market structure bill, known as the Clarity Act. Due to constraints imposed by Senate rules, completing deliberations on this bill before the August 7 recess is highly unlikely. According to Senate rules, once a cloture (a vote to end debate) is invoked and passed, the bill in question becomes a 'pending business' and takes precedence over all other deliberations, preventing the advancement of any other contested bills simultaneously.
