WASHINGTON AP – The Justice Department will investigate the proposed merger of ticketing giant Ticketmaster Entertainment Inc. with Live Nation Inc. to see if the combined company would create an unfair monopoly in the ticket-selling business.

Federal antitrust lawyers are “committed to vigorous enforcement of the merger antitrust laws and will conduct a thorough investigation of the proposed Ticketmaster/Live Nation transaction,” said Justice Department spokeswoman Gina Talamona.
