A Senate subcommittee on investigations issued a subpoena looking to force the concert giant to submit documents on ticket prices and fees

A Senate subcommittee issued a subpoena to live music giant Live Nation Entertainment late last week, seeking documents related to ticket prices and fees listed on Ticketmaster.

The subpoena, obtained by Rolling Stone, comes eight months after the Senate’s Permanent Subcommittee on Investigations first launched an inquiry into Live Nation over the company’s “business practices, including the prices and fees for tickets to live events sold by Live Nation/Ticketmaster,” requesting the documents related to that inquiry on March 24th. That inquiry hadn’t been publicly reported prior to the subpoena filing, as the company faces broader regulatory scrutiny over potential antitrust concerns.

But as Subcommittee chairman Sen. Richard Blumenthal (D-Conn.) claimed in the subpoena last week, the company hasn’t cooperated with the request to this point. “Despite nearly eight months and extensive efforts to obtain voluntary compliance, Live Nation/Ticketmaster has failed to fully comply with PSI’s requests, including refusing to produce certain documents critical to the Subcommittee’s inquiry,” Blumenthal wrote.
