The U.S. Senate's Permanent Subcommittee on Investigations subpoenaed Live Nation Entertainment for documents related to ticket prices and fees. Despite previous requests, Live Nation has not fully complied, citing the need for confidentiality provisions. The subpoena seeks information on pricing, fees, resale practices, and the company's relationship with artists and venues. Live Nation faces broader regulatory scrutiny, including a DOJ investigation into its market dominance. The company has denied operating as a monopoly and has called for legislative reforms in ticketing.
