The committee sought documents pertaining to the ticketing policies of Live Nation, Anschutz Entertainment Group (AEG), eBay's (EBAY) - Get Report StubHub, Vivid Seats, TicketNetwork, and Major League Baseball's Tickets.com.
The committee's concerns include "high, hidden fees, speculative tickets that harm unknowing customers, and 'white label' websites that may use practices to deceive consumers," according to the release.
