The Senate investigative subcommittee has issued a subpoena to Live Nation and its subsidiary Ticketmaster for information on ticket pricing and fees. The subcommittee's chairman, Sen. Richard Blumenthal, accused Live Nation of failing to combat inflated ticket prices caused by bots. The subpoena requests records related to this issue. Live Nation and Ticketmaster control 70% of the ticket market, and the investigation began after controversies over ticket sales for concerts by Taylor Swift and Bruce Springsteen. The subpoena also seeks documents on ticket pricing, fees, resale practices, and the companies' relationships with artists and venues. Live Nation has been accused of stonewalling the inquiry.
